DESC:VEHICLE HILL ASSIST CONTROL SYSTEM
CROSS REFERENCE TO RELATED APPLICTIONS
The present application claims priority from Indian Provisional Patent Application No. 202321065118 filed on 28/09/2023, the entirety of which is incorporated herein by a reference.
TECHNICAL FIELD
Generally, the present disclosure relates to a hill assist control system in vehicle(s). Particularly, the present disclosure relates to a system and method for preventing rolling down of an electric vehicle on an inclined surface.
BACKGROUND
Hill assist technology in a vehicle refers to an assistance feature developed to prevent the vehicle from rolling downwards on an incline surface. The hill assist technology enables the rider to smoothly manage starting and stopping of the vehicle on the inclined surface.
Conventionally, electric vehicles employ a brake hold function to prevent the vehicle from rolling downwards on an inclined surface. The brake hold function maintains the brake pressure temporarily after the rider releases the brake (on the inclined surface). The temporary brake pressure holds the electric vehicle in place and prevents it from rolling downwards. Further, the brake hold function is activated manually or automatically. Specifically, the automatic brake hold function activates automatically when the vehicle is completely stopped and/or brake pedal is pressed multiple times (in a predefined time interval). The manual brake hold function requires the rider to manually activate the brake hold function using a button or a switch.
However, there are certain underlining problems associated with the above-mentioned existing hill assist technology. For instance, when the brake pedal is pressed multiple times (in a predefined time interval) even on a plane surface, the automatic brake hold function gets activated. Further, the activation of the brake hold function may be a delayed based on the time interval of the brake application. Therefore, the imperfect activation/deactivation of the brake hold function can affect the smoothness of the transition from a stop to acceleration of the vehicle on the inclined surface. Further, the delay in the activation of the brake hold function also develops a challenge for the safety of the vehicle on the inclined surface (especially on the hilly surface).
Therefore, there exists a need for a hill assist control system in a vehicle that is safe and overcomes one or more problems as mentioned above.
SUMMARY
An object of the present disclosure is to provide a system for preventing rolling down of an electric vehicle on an inclined surface.

As used herein, the terms “rolling down”, and “spinning down” are used interchangeably and refer to a tendency of an object to move in a downward direction along the slope of the inclined surface (irrespective of direction of its motion). The rolling down on the inclined surface primarily occurs because of the gravitational force acting down the incline surface.
As used herein, the terms “electric vehicle”, “vehicle”, and “EV” are used interchangeably and refer to a vehicle that is driven by an electric motor that draws its electrical energy from a battery and is charged from an external source. The electric vehicle includes both a vehicle that is only driven by the electric motor that draws electrical energy from the battery (all-electric vehicle) and a vehicle that may be powered by an electric motor that draws electricity from the battery and by an internal combustion engine (hybrid vehicle). Moreover, the ‘electric vehicle’ as mentioned herein may include electric two-wheelers, electric three-wheelers, electric four-wheelers, electric trucks, electric pickup trucks, and so forth.
As used herein, the terms “inclined surface”, “hilly surface”, “slope”, “ramp”, and “tilted surface” are used interchangeably and refer to a sloped plane or surface that forms an angle ? with the horizontal surface. The angle of inclination affects the gravitational and frictional force acting on object(s) placed on the surface. Examples of inclined surface may include (but not limited to) ramps, sloped driveways, and tilted roads.
As used herein, the term “vehicle orientation detection module” refers to a detection module designed to monitor and provide vehicle orientation information relative to the horizontal/vertical plane.

The vehicle orientation detection module includes accelerometers, gyroscopes, and magnetometers. The accelerometers measure linear acceleration, gyroscopes measure rotational rates, and magnetometers determine orientation relative to the earth's magnetic field.
As used herein, the term “speed sensor” refers to a device that detects the vehicle real-time speed information. The speed information of the vehicle is used for monitoring, controlling, and safety purposes of the vehicle. The speed sensors employ the magnetic effect principle, wherein the magnetic field is disrupted by a rotating metal object (like a gear or rotor). The sensor detects the disruptions and converts them into electrical signals.
As used herein, the term “throttle sensor” refers to a device that detects an input provided by the rider and communicates this information to the vehicle control systems.
As used herein, the term “break position sensor” refers to a device that detects the position and application of the brake in a vehicle.

In accordance with a first aspect of the present disclosure, there is provided a system for preventing rolling down of an electric vehicle on an inclined surface, the system comprises:
- a vehicle orientation detection module;
- at least one speed sensor;
- a throttle sensor;
- a break position sensor; and
- a control unit communicably coupled with the vehicle orientation detection module, at least on speed sensor, the throttle sensor, and the break position sensor,
wherein the vehicle orientation detection module is configured to detect an angle of the electric vehicle and a direction of movement of the electric vehicle.
Referring to figure 1, in accordance with an embodiment, there is described a system 100 for preventing rolling down of an electric vehicle 102 on an inclined surface. The system 100 comprises a vehicle orientation detection module 104, at least one speed sensor 106, a throttle sensor 108, a break position sensor 110 and a control unit 112. Specifically, the control unit 112 is communicably coupled with the vehicle orientation detection module 104, at least one speed sensor 106, the throttle sensor 108, and the break position sensor 110. Further, the vehicle orientation detection module 102 is configured to detect an angle of the electric vehicle 102 and a direction of movement of the electric vehicle 102.
The vehicle orientation detection module 104 of the system 100, is configured to detect the angle of the electric vehicle 102 and the direction of movement of the electric vehicle 102 (on the inclined surface o-o’). The detection of the direction enables the control unit 112 to determine the direction of the rolling down (forward or backward) of the vehicle. Further, the detected angle of the vehicle on the inclined surface (o-o’) is received by the control unit 112 and compared with the threshold vehicle angle range. Subsequently, based on the comparison, and the direction of the movement of the vehicle, the control unit 112 determines the counter torque required to neutralize the rolling down of the vehicle. Beneficially, applying the counter-torque enhances the vehicle control on the steep inclined surfaces, and therefore, preventing the uncontrolled sliding or rolling of the vehicle. Consequently, the risk of accidents caused by sudden or unexpected vehicle movements on slopes is reduced. Further, the need for constant braking on the inclined surface (o-o’) is also reduced, thereby, prolonging the lifespan of the brake components.
Referring to figure 2A and figure 2B, in accordance with different embodiments, depicts visual representation of an electric vehicle 102 on an inclined surface. Specifically, figure 2A depicts the electric vehicle 102 moving upwards on the inclined surface (o-o’) (and backward rolling). Further, figure 2B depicts the electric vehicle 100 moving downwards on the inclined surface (o-o’) (and forward rolling). The axis x-x’ is parallel to the inclined surface and axis y-y’ is perpendicular to the inclined surface. Further, the axis a-a’ is longitudinal line passing through the centre of the vehicle. Furthermore, the angular deviation ? is the angle between the vehicle’s longitudinal axis (a-a’) and the vertical axis (y-y’) surface.
In an embodiment, the vehicle orientation detection module 104 detects the angle of the electric vehicle 102 with respect to the inclined surface. Based on the direction of the movement of the vehicle, the detected angle is positive angle or negative angle. Further, the detected angle of the vehicle on the inclined surface (o-o’) is received by the control unit 112 and compared with the threshold vehicle angle range. Subsequently, based on the comparison, and the direction of the movement of the vehicle, the control unit 112 determines the counter torque required to counterbalance the rolling down.
In an embodiment, the detected angle of the electric vehicle 102 is an angular deviation with respect to a vertical axis of the electric vehicle. The angular deviation ? of the vehicle from the vertical axis (y-y’) is the same as the angle of the ramp of the inclined surface. Therefore, the angular deviation enables the identification of the vehicle deviation from the vertical axis (y-y’) and the angle of the ramp of the inclined surface. Beneficially, based on the detected angle, the control unit 112 initiates the hill assist mechanism.
In an embodiment, the vertical axis is perpendicular to the inclined surface. The vertical axis (y-y’) is perpendicular to the inclined surface and provides a clear and accurate reference point for measuring the vehicle’s angular deviation. Further, a consistent reference point for angle measurements ensures improved reliability for the operation of the control unit 112.
In an embodiment, the control unit 112 is configured to receive data from the vehicle orientation detection module 104, at least one speed sensor 106, the throttle sensor 108, and the break position sensor 110. The control unit 112 is configured to receive the vehicle angle and direction via the vehicle orientation detection module 104. Further, the detected angle is compared with the threshold angle range of the vehicle on the inclined surface (o-o’). Further, the control unit 112 is configured to receive the speed of the vehicle, the throttle input, and the break position. Consequently, the hill assist mechanism is activated when the speed of the vehicle, and the throttle input approaches zero, brakes of the vehicle are being engaged and simultaneously the detected angle is above the threshold angle range. Therefore, the receiving of the data by the control unit 112 ensures the on-time activation of the hill assist mechanism.
In an embodiment, the control unit 112 is configured to receive the detected angle and compare the received angle with a threshold vehicle angle range. The comparison of the detected angle with a predefined threshold angle range enables the control unit 112 to identify the operational limits (above or below the threshold) of the vehicle. Consequently, the comparison enables the control unit 112 to activate or deactivate the hill assist mechanism to prevent the rolling down of the vehicle on the inclined surface (o-o’).
In an embodiment, the control unit 112 is configured to determine a forward rolling down or a backward rolling down, of the electric vehicle 102, based on the data received from the vehicle orientation detection module 104, at least on speed sensor 106, the throttle sensor 108, and the break position sensor 110. Based on the received data, the control unit 112 identifies the angular deviation ? of the vehicle. Further, the angular deviation ? is positive or negative, based on the direction of the rolling (forward or backward). The angular deviation ? is positive for backward rolling and negative for forward rolling. Therefore, based on the direction of the rolling down, the control unit 112 determines the direction of the required counter torque.
In an embodiment, the control unit 112 is configured to determine counter torque required to neutralize the forward rolling down or the backward rolling down. The counter torque is the opposing torque applied by the motor 116 to balance the rolling down tendency of the vehicle. Beneficially, the accurate counter torque enables prevention of roll-over(s) by maintaining the vehicle’s stability on steep inclines or declines. Further, the counter torque ensures the complete stoppage of the vehicle without rolling backward or forward on inclines, providing a safer operation during start and stop, of the vehicle, on the inclined surface (o-o’).
Referring to figure 3, in accordance with an embodiment, there is described a system 100 for preventing rolling down of an electric vehicle on an inclined surface. The system comprises a vehicle orientation detection module 104, at least one speed sensor 106, a throttle sensor 108, a break position sensor 110 and a control unit 112. Further, the electric vehicle 102 comprises a motor controller 114 and a motor 116. Specifically, the control unit 112 is communicably coupled with the motor controller 114 of the electric vehicle 102. The motor controller 114 is configured to receive the detected counter torque and enable a motor 116 of the electric vehicle to supply the counter torque.
In an embodiment, the control unit 112 is communicably coupled with a motor controller 114 of the electric vehicle 102. The coupling of the control unit 112 with the motor controller 114 enables the control unit 112 to directly adjust the torque (counter torque) based on real-time conditions. Therefore, the coupling of the control unit 112 with the motor controller 114 results in more responsive and efficient performance of the vehicle on the inclined surface (o-o’).
In an embodiment, the motor controller 114 receives the detected counter torque and applies the received counter torque to counteract or balance the torque produced by the rolling down tendency of the vehicle (on the inclined surface (o-o’). Consequently, the vehicle is held in place, thereby, preventing rolling down of the vehicle. Therefore, the application of the counter torque maintains the stability, control, and safety of the vehicle on the inclined surface (o-o’).
In an exemplary embodiment, the vehicle orientation detection module 104 is configured to detect the angle of the electric vehicle 102 with respect to the inclined surface (o-o’). Specifically, in this embodiment the angular deviation ? of the vehicle in the range of positive 5 degrees to negative 5 degrees (5° < ? < -5°). Further, the hill assist mechanism is self-activated when the angle ? ranges between 5° < ? < -5°, the throttle input approaches zero, as speed of the vehicle is less than 5 kmph and the brakes of the vehicle are being engaged. Consequently, the control unit 112 enables the motor 116 to apply the counter torque to balance the rolling down tendency of the vehicle, and thereby, preventing rolling down of the vehicle.
In accordance with a second aspect, there is described a method 200 of preventing rolling down of an electric vehicle 102 on an inclined surface, the method comprises:
- receiving data from an vehicle orientation detection module 104, at least one speed sensor 106, a throttle sensor 108, and a break position sensor 110, to a control unit 112;
- detecting an angle and a direction of movement, of the electric vehicle, by the control unit 112;

- determining counter torque required to neutralize the forward rolling down or the backward rolling down, by the control unit 112; and
- communicating the counter torque requirement to a motor controller of the electric vehicle, by the control unit 112.

At the step 202, the method comprises receiving data from an vehicle orientation detection module, at least one speed sensor, a throttle sensor, and a break position sensor, to a control unit.
