DESC:[001] The present disclosure generally relates to a panic brake detection and warning system and method of manufacturing thereof. Particularly it relates to the panic brake detection and warning system for the trailer based commercial vehicles and method of manufacturing thereof
[002] The existing commercial vehicle does not comprise a detection or broadcasting system to identify or detect the panic brake to the trailing vehicles. With the large rear surface area and length of commercial vehicles, it is impossible for the trailing vehicle to perceive any dangers ahead. In the event of an emergency braking, when the CV panic brakes, it is relatively difficult for the trailing vehicle to perceive the sudden high rate of deceleration. With a reduced reaction time and distance, it is very common for the trailing vehicle to collide with another vehicle or external agencies.
[003] In the unlikely event of a rear end collision, both vehicles suffer from significant damage. In the attempt to restore vehicular functional or aesthetic features prior to impact, it requires significant downtime and cost. The only way around this situation is to prevent the accident in the first place.
[004] Further with many variants in a fleet is required to communize a product for cross platform and backward compatibility, hence the present stated invention is designed to be applicable across the truck and bus range, with an available CAN communication. A singular device is illustrated with no additional vehicle specific fitment or components.
[005] Hence there is a need of panic brake detection and warning system to avoid the accident in the trailer type commercial vehicle.
[006] The present subject matter solves the aforementioned and other problems, where the safety aspects of a vehicle do not confine to just the driver and occupants but also extend to the surrounding vehicle and pedestrians. Efficient braking systems allow a commercial vehicle to stop instantaneously on detecting a potential threat ahead. While this prevents the occurrence of an impending disaster ahead, the inability of the trailing vehicles to perceive the sudden deceleration often results in rear-ended collision of the leading vehicle. Unlike trailing a passenger vehicle, the large rear surface area of a commercial vehicle impairs the vision of the trailing vehicle, and it has to operate based on perceived speeds and tail-light indications. In developing markets with a significant two-wheeler population, the incidents of rear-ended collisions prove detrimental for the vehicle as well as the riders. In the interest to reduce fatalities and vehicular damage, the utility of the taillight of the leading commercial vehicle is further utilized to produce an indication to the trailing vehicles, in the unlikely event of panic braking. Utilizing vehicular speed data from the CAN-Bus, a controller determines instantaneous deceleration beyond a set speed of the vehicle. Further, based on typical deceleration rates, a threshold deceleration value is set in the controller. While braking if the observed instantaneous deceleration value exceeds the threshold value, the presence of a panic braking is observed by the controller and immediately the hazard lights are switched on to caution the trailing vehicles in order to make necessary maneuvers. By alerting the trailing vehicles, the probability of a rear-end impact, detrimental to both the leading and trailing vehicle is significantly reduced thereby improving the overall safety envelope of the vehicle.
[007] FIG 1. illustrates the controller schematic of the panic brake detection and warning system controller. The controller is powered using the vehicles onboard power supply system. The detection of vehicle operation is signaled by the presence of ignition signal to the controller. The data for the vehicle speed is obtained from the vehicle on board CAN bus using the 250kbps communication channel.
[008] Post obtaining vehicle speed the controller computes instantaneous time derivative from the speed data to determine vehicle acceleration. A two-step conditional algorithm is utilized to detect the presence of a panic brake. The conditions are listed as:
Vehicle speed above 40Km/h
Deceleration <-3.5 m/s2
[009] Post detection of the above criteria confirms the initialization a panic brake, and the controller immediately signals the vehicle’s flasher controller to turn on the hazard lights to warn the trailing vehicles. At the same time the number of panic braking events per time duration is also recorded. On detection of multiple panics braking within a short duration, poor driver behavior is overserved, and immediate situation report is relayed to vehicle owner through the telematics unit. Through this process the vehicle owner is aware of the vehicle driving style and can take interventory actions, to safeguard his vehicle and cargo.
[0010] In another embodiment, the present subject matter provides a detection and warning of panic braking situation to alert trailing vehicles. It improves response time and distance for safer braking of trailing vehicles. Thereby reduces accident repair related downtime of both vehicles.
[0011] From the safety points of views, it improved safety envelope of vehicle and detect the misbehavior/poor vehicle handling by driver.
[0012] It also is having backward and universally cross compatible, with direct fitment. It is a single unit design, with no additional sensors.
[0013] The panic braking detected during the braking process; warning is relayed to trailing vehicle even before complete braking is complete. Here panic braking is detected from true deceleration value of vehicle, with system operating only in the event of panic braking, with reduced cases of false alarms.
[0014] It is a software centric system utilizing vehicles onboard data to analyze and predict the panic braking event. Vehicle onboard sensor is on contact in nature, with reduced number of failures as compared to pressure transducers and switches compactible to all types of the vehicles.
[0015] The present subject matter is having implementation of instantaneous panic brake detection and warning system on vehicle. Here the algorithm-centric system requiring no addition hardware, with precise panic braking detection. Without utilizing no modifications in the fitment strategy and wiring harness. It is a single standalone product.
[0016] Further it prevents vehicle damage due to collision, by warning trailing vehicles through hazard illumination. Therefore, informing vehicle owner on detection of repeated panic braking events to safeguard vehicle and cargo.
[0017] It has a utility of continuously measure vehicle instantaneous acceleration/deceleration to determine – (a) the initiation of a panic brake, to illuminate the hazard indicators to wan trailing vehicles and allow sufficient reaction time to maneuver out of an impending frontal impact and (b) compute the number of panic braking events occurring with a time interval to determine the behavioral tendency of the driver and notify owner in the event of detection of poor driving ethics.
