Description:FIELD OF THE INVENTION
[001] The present invention relates to a vehicle. More particularly, the present invention relates to an overtake assistance system and method for a host vehicle.

BACKGROUND OF THE INVENTION
[002] Generally, a rider of a host vehicle overtakes one or more preceding vehicles by gauging a situation himself/herself. Multiple decisions are made by the rider in a short span of time such as analysing safe distance to overtake, relative speed of one or more preceding vehicles in same/adjacent lanes etc. Such decisions may not always be accurate and can lead to accidents, which is highly undesirable. The overtaking decisions becomes critical in scenarios where there is no divider to separate the left lanes and the right lanes. In such scenarios, the rider of the vehicle has to take into consideration not only the preceding and following vehicles but also oncoming vehicles which makes the decision to overtake even more difficult and increases the chances of accidents/collision.
[003] The prior arts have attempted to solve the problems by providing a suggestion or a notification to the rider to the host vehicle for safe overtake. However, no assistance is provided to the rider of the host vehicle for safely overtaking the one or more preceding vehicles.
[004] In view thereof, there is a need felt to overcome at least the above-mentioned disadvantages and provide an overtake assistance system and method which is simple, reliable and cost effective.

[008] Various features and embodiments of the present invention here will be discernible from the following further description thereof, set out hereunder.
[009] Figure 1 illustrates a block diagram of an overtake assistance system for a host vehicle, in accordance with an embodiment of the present invention.
[010] For the purpose of the present invention, the term “host vehicle”, “preceding vehicle”, “following vehicle” and “oncoming vehicle” comprises saddle type vehicles as well as passengers vehicles such as, not being limited to, bicycles, scooters, motorcycles, rickshaws, cars, trucks, etc. The term “host vehicle”, “preceding vehicle”, “following vehicle” and “oncoming vehicle” also comprises, not being limited to, conventional internal combustion engine vehicles, electric vehicles and hybrid vehicles.
[011] The construction and working of the different components of the saddle type vehicles and passenger vehicles are already known in the art and have not been discussed in detail for the sake of brevity. However, this should not be construed as limiting to the scope of the present invention.
[012] As shown in Figure 1, the overtake assistance system 10 comprises one or more first devices 12, one or more second devices 14, one or more third devices 16 and a control unit 18. The one or more first devices 12 are mounted on the host vehicle 100 and configured to capture images and/or videos of one or more preceding vehicles 200, one or more following vehicles 300 and one or more oncoming vehicles 400. In one non-limiting example, the one or more first devices 12 are image capturing units and/or video capturing unit such as, not being limited to camera. It is to be understood that the one or more first devices 12 have a field of view for capturing the one or more preceding vehicles 200, the one or more following vehicles 300 and the one or more oncoming vehicles 400. The one or more first devices 12 are generally provided at the front end and rear end of the host vehicle 100. However, this should not be construed as limiting and the cameras can also be mounted on left side and/or right side of the host vehicle 100 to capture images and/or videos of one or more preceding vehicles 200, one or more following vehicles 300 and one or more oncoming vehicles 400.
[013] The one or more second devices 14 are mounted on the host vehicle 100 and configured to detect a first set of pre-defined parameters in relation to the one or more preceding vehicles 200, the one or more following vehicles 300 and the one or more oncoming vehicles 400. In one non-limiting example, the second device 14 comprises sensors such as LIDAR sensor and/or RADAR sensor. In one non-limiting example, the first set of pre-defined parameters comprises speed of the one or more preceding vehicles 200, acceleration of the one or more preceding vehicles 200, deacceleration of the one or more preceding vehicles 200, lane of the one or preceding vehicles 200, distance of the one or more preceding vehicles 200 from the host vehicle 100, speed of the one or more following vehicles 300, acceleration of the one or more following vehicles 300, deacceleration of the one or more following vehicles 300, lane of the one or more following vehicles 300, distance of the one or more following vehicles 300 from the host vehicle 100, speed of the one or more oncoming vehicles 400, acceleration of the one or more oncoming vehicles 400, deacceleration of the one or more oncoming vehicles 400, lane of the one or more oncoming vehicles 400 and/or distance of the one or more oncoming vehicles 400 from the host vehicle 100. However, this should not be construed as limiting and other vehicular parameters of the one or more preceding vehicles 200, the one or more following vehicles 300 and the one or more oncoming vehicles 400 which may be necessary for determining overtake conditions for the host vehicle 100 can be captured by the one or more second devices 14. The one or more first devices 12 and the one or more second devices 14 assist in accurately capturing the size, dimensions and above-mentioned parameters of the one or more preceding vehicles 200, one or more following vehicles 300 and one or more oncoming vehicles 400.
[014] The one or more third devices 16 are mounted on the host vehicle 100 and configured to detect a second set of pre-defined parameters in relation to the host vehicle 100. In a non-limiting example, the third device 16 comprises a speed sensor, a lean angle sensor and an inertial measurement unit (IMU). In a non-limiting example, the second set of pre-defined parameters comprises vehicle altitude information and/or vehicle attitude information. The vehicle attitude information comprises speed of the host vehicle 100, lean angle of the host vehicle 100 (in case of saddle type vehicles), steering angle of the host vehicle 100 (in case of passenger vehicle) and/or throttle value of the host vehicle 100. The vehicle altitude information is altitude information of the host vehicle 100. The vehicle altitude information is tracking of the position of the host vehicle 100 above the mean sea level based on a Global Positioning Sensor (GPS) and using that data to assist with navigation and safety of the host vehicle 100. The one or more third devices 16 essentially captures information required for determining a safe overtake condition for the host vehicle 100 and may additionally include sensors which provide information with respect to different components of the host vehicle 100 such as battery, gears, clutch etc.
[015] The control unit 18 is mounted on the host vehicle 100 and communicatively coupled to the one or more first devices 12, the one or more second devices 14 and the one or more third devices 16. The control unit 18 is configured to receive captured images/videos from the one or more first devices 12, the first set of pre-defined parameters from the one or more second devices 14 and the second set of pre-defined parameters from the one or more third devices 16. Upon receiving the same, the control unit 18 is configured to process captured images/videos, the first set of pre-defined parameters and the second set of the pre-defined parameters to determine satisfaction of pre-defined conditions. Upon satisfaction of the pre-defined conditions, the control unit 18 instructs one or more pre-defined components 22 of the host vehicle 100 to provide additional torque to the host vehicle 100 for overtaking the one or more preceding vehicles 200 for a pre-defined period of time. The pre-defined period of the time is the time required for overtaking the one or more preceding vehicles 200. In a non-limiting example, the pre-defined components 22 of the host vehicle 100 are internal combustion engine and/or a battery operated electric motor.
[016] One or more pre-defined conditions may be specified by the manufacturer of the host vehicle 100/control unit 18 to facilitate accuracy and safety in overtaking the one or more preceding vehicles 200. The various pre-defined conditions have been discussed in detail in Figure 2a to 2i. However, this should not be construed as limiting and other conditions to facilitate accuracy in overtaking the one or more preceding vehicles 200 may be defined by the manufacturer of the host vehicle 100/control unit 18.
[017] Figure 2a illustrates a first working example where torque assistance is provided to the host vehicle 100 for overtaking a preceding vehicle 200 in same lane L as host vehicle 100, in accordance with an embodiment of the present invention.
[018] As shown, the preceding vehicle 200 is in the same lane L as the host vehicle 100. The control unit 18 allows the host vehicle 100 to overtake the preceding vehicle 200 only upon satisfaction of pre-defined conditions. One of the pre-defined conditions being mode of the host vehicle 100 which is selected by the rider of the host vehicle 100. The host vehicle 100 operates in at least two modes. The first mode is a normal mode wherein the overtake assistance system 10 is deactivated. The second mode is a torque assistance mode, on selection of which additional torque/torque assistance is provided to the host vehicle 100 upon determination of an overtake condition. The control unit 18 allows the torque/overtake assistance only when the host vehicle 100 is in torque assistance mode. In one non-limiting example, the rider of the host vehicle 100 will be provided with an option to deactivate the overtake/torque assistance on the instrument cluster 20 in case the rider does not wish to overtake the one or more preceding vehicle in torque assistance mode. The control unit 18 will also determine whether the speed of the host vehicle 100 is greater than the speed of the preceding vehicle 200 which is in the same lane L as the host vehicle 100 and which the host vehicle 100 intends to overtake. The control unit 18 will also determine absence of the one or more preceding vehicle 200, the one or more following vehicles 300 and the one or more oncoming vehicles 400 in an overtake lane OL. The overtake lane OL is a lane adjacent to the lane L of the host vehicle 100 and will be used by the host vehicle 100 to overcome the preceding vehicle 200. The control unit 18 will also determine the intention of the rider of the host vehicle 100 to overtake the preceding vehicle 200.
[019] In case of host vehicle 100 being saddle type vehicle, the intention of rider is generally determined by lean angle of the host vehicle 100 and the throttle value of the host vehicle 100. When the rider of the saddle type vehicle has an intention to overtake, the host vehicle 100 has a pre-defined lean angle and the throttle value of the vehicle is greater than a pre-defined throttle value. In one non-limiting example, the pre-defined lean angle has a value in a range of up to 30 degrees measured from the vehicle vertical axis in both left and right direction of the saddle type vehicle. In case of passenger vehicle, the intention of rider is generally determined by steering angle of the host vehicle 100 and the throttle value of the host vehicle 100. When the rider of the passenger vehicle has an intention to overtake, the host vehicle 100 has a pre-defined steering angle and the throttle value of the host vehicle 100 is greater than a pre-defined throttle value. In one non-limiting example, the pre-defined steering angle has a value in a range of 2 degrees to thirty degrees from a neutral position of the steering wheel in both left and right direction of the passenger vehicle. The control unit 18 can additionally refer to the riding patterns of the rider of the host vehicle 100 in order to assess the intention of the rider to overtake the one or more preceding vehicles 200. The riding patterns can be stored in control unit of the host vehicle 100.
[020] The throttle parameter indicates a scenario where the rider accelerates to a point beyond the pre-defined throttle value and the system identifies that an overtake is taking place and hence, provides the torque/overtake assistance.
[021] Upon satisfaction of the above-mentioned pre-defined conditions, additional torque will be provided by the one or more pre-defined components 22 of the vehicle to overtake the preceding vehicle.
[022] Figure 2b illustrates a second working example where torque assistance is provided to the host vehicle 100 for overtaking a plurality of preceding vehicles 200 in same lane L as host vehicle 100, in accordance with an embodiment of the present invention.
[023] As shown, plurality of preceding vehicles 200 are in the same lane L as the host vehicle 100. The control unit 18 allows the host vehicle 100 to overtake the plurality of preceding vehicles 200 only upon satisfaction of pre-defined conditions. One of the pre-defined conditions being mode of the host vehicle 100 which is selected by the rider of the host vehicle 100. The host vehicle 100 operates in at least two modes. The first mode is a normal mode wherein overtake assistance system 10 is deactivated. The second mode is a torque assistance mode, on selection of which additional torque/torque assistance is provided to the host vehicle 100 upon detection of the overtake condition. The control unit 18 allows the overtake/torque assistance only when the host vehicle 100 is in torque assistance mode. In one non-limiting example, the rider of the host vehicle 100 will be provided with an option to deactivate the torque assistance on the instrument cluster 20 in case the rider does not wish to overtake the one or more preceding vehicles 200 in torque assistance mode. The control unit 18 will also determine whether the speed of the host vehicle 100 is greater than the speed of each of the plurality of the preceding vehicles 200 which is in the same lane as the host vehicle 100 and which the host vehicle 100 intends to overtake. The control unit 18 will also determine absence of the one or more preceding vehicle 200, the one or more following vehicles 300 and the one or more oncoming vehicles 300 in an overtake lane OL. The overtake lane OL is a lane adjacent to the lane L of the host vehicle 100 and will be used by the host vehicle 100 to overcome the plurality of the preceding vehicles 200. The control unit 18 will also determine the intention of the rider of the host vehicle 100 to overtake the one or more preceding vehicles 200.
[024] In case of host vehicle 100 being saddle type vehicle, the intention of rider is generally determined by lean angle of the host vehicle 100 and the throttle value of the host vehicle 100. When the rider of the saddle type vehicle has an intention to overtake, the host vehicle 100 has a pre-defined lean angle and the throttle value of the vehicle is greater than a pre-defined throttle value. In one non-limiting example, the pre-defined lean angle has a value in a range of up to 30 degrees measured from the vehicle vertical axis in both left and right direction of the saddle type vehicle. In case of passenger vehicle, the intention of rider is generally determined by steering angle of the host vehicle 100 and the throttle value of the host vehicle 100. When the rider of the passenger vehicle has an intention to overtake, the host vehicle 100 has a pre-defined steering angle and the throttle value of the host vehicle 100 is greater than a pre-defined throttle value. In one non-limiting example, the pre-defined steering angle has a value in a range of 2 degrees to thirty degrees from a neutral position of the steering wheel in both left and right direction of the passenger vehicle. The control unit 18 can additionally refer to the riding patterns of the rider of the host vehicle 100 in order to assess the intention of the rider to overtake the one or more preceding vehicles 200. The riding patterns can be stored in control unit of the host vehicle 100.
[025] Upon satisfaction of the above-mentioned pre-defined conditions, additional torque will be provided by the one or more pre-defined components 22 of the host vehicle 100 to overtake the one or more preceding vehicles 200.
[026] Figure 2c illustrates a third working example where torque assistance is provided to the host vehicle 100 for overtaking a preceding vehicle 200 in same lane L as host vehicle 100, in accordance with an embodiment of the present invention.
[027] As shown, one or more preceding vehicles 200 are in the same lane L as the host vehicle 100. The control unit 18 allows the host vehicle 100 to overtake the one or more preceding vehicles 200 only upon satisfaction of pre-defined conditions.

The second mode is a torque assistance mode, on selection of which additional torque/torque assistance is provided to the host vehicle 100 upon determination of the overtake condition. The control unit 18 allows the overtake assistance only when the host vehicle 100 is in torque assistance mode. In one non-limiting example, the rider of the host vehicle 100 will be provided with an option to deactivate the torque assistance on the instrument cluster 20 in case the rider does not wish to overtake the one or more preceding vehicles 200 in torque assistance mode. The control unit 18 will also determine whether the speed of the host vehicle 100 is greater than the speed of each of the plurality of the preceding vehicles 200 which is in the same lane L as the host vehicle 100 and which the host vehicle 100 intends to overtake. The control unit 18 will also determine whether distance of the host vehicle 100 from the nearest oncoming vehicle 400 in an overtake lane OL is greater than a first pre-defined distance. The overtake lane OL is a lane adjacent to the lane L of the host vehicle 100 and will be used by the host vehicle 100 to overcome the one or more preceding vehicles 200. The control unit 18 will also determine whether the speed of the host vehicle 100 is greater than the nearest oncoming vehicle 400 in the overtake lane OL. The control unit will also determine absence of the one or more following vehicles 300 in the overtake lane OL within a second pre-defined distance of the host vehicle 100. It is to be understood that the first pre-defined distance and the second pre-defined distance are decided keeping in view governmental rules and regulations and to facilitate safe overtake. The control unit 18 will also determine the intention of the rider of the host vehicle 100 to overtake the preceding vehicle 200.
[028] In case of host vehicle 100 being saddle type vehicle, the intention of rider is generally determined by lean angle of the host vehicle 100 and the throttle value of the host vehicle 100. When the rider of the saddle type vehicle has an intention to overtake, the host vehicle 100 has a pre-defined lean angle and the throttle value of the vehicle is greater than a pre-defined throttle value. In one non-limiting example, the pre-defined lean angle has a value in a range of up to 30 degrees measured from the vehicle vertical axis in both left and right direction of the saddle type vehicle. In case of passenger vehicle, the intention of rider is generally determined by steering angle of the host vehicle 100 and the throttle value of the host vehicle 100. When the rider of the passenger vehicle has an intention to overtake, the host vehicle 100 has a pre-defined steering angle and the throttle value of the host vehicle 100 is greater than a pre-defined throttle value.
