An active rollover protection (ARP), is a system that recognizes impending rollover and selectively applies brakes to resist. [1] ARP builds on electronic stability control and its three chassis control systems already on the vehicle – anti-lock braking system, traction control and yaw control. ARP adds another function: detection of an ...
There are four main components of ABS: wheel speed sensors, valves, a pump, and a controller. ABS speed sensors Speed sensors (Encoders) A speed sensor is used to determine the acceleration or deceleration of the wheel. These sensors use a magnet and a Hall effect sensor, or a toothed wheel and an electromagnetic coil to generate a signal. The ...
The most important sensors are as follows: A steering wheel angle sensor that determines where the driver wants to steer. This kind of sensor often uses AMR elements. A yaw rate sensor that measures the rotation rate of the car. The data from the yaw sensor is compared with the data from the steering wheel angle sensor to determine regulating ...
Wheel Slide Protection (WSP) equipment is generally fitted to passenger trains to manage the behavior of wheel sets in “low adhesion” (reduced wheel/rail friction) conditions. It is used when braking and may be considered analogous to anti-lock braking (ABS) in cars. The system can also be used to control (or provide an input to) the ...
This is also the case if any of the system components are subsequently changed e.g. in the event of rotating the tires, changing sensors, replacing the ECU etc. [4] This process requires the activation of the direct TPMS sensor using low frequency (LF) radio and the capture of the UHF data transmitted. This data includes the direct TPMS ID, the ...

A radar sensor in the rear bumper monitors the traffic behind the vehicle. If the risk of an impact from the rear is detected, the rear hazard warning lights are activated to alert the driver of the vehicle behind (not on vehicles with USA/Canada coding). Anticipatory occupant protection measures, such as the reversible belt tensioners, are ...
