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 ...
direct TPM sensor fitted in valve system, manufacturer VDO. In most current designs of direct TPMS, a small electronic assembly which is rugged enough to be mounted inside a tire, measures the pressure using a microelectromechanical system (MEMS) [1] pressure sensor and then transmits this and other information to one or more vehicle receivers. [1]
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 ...
Indirect TPMS (iTPMS) systems do not use physical pressure sensors; they measure air pressures using software-based systems, which by evaluating and combining existing sensor signals such as wheel speeds, accelerometers, and driveline data to estimate and monitor the tire pressure without physical pressure sensors in the wheels.
Electronic stability control (ESC) can reduce the speed of the car and activate individual brakes to prevent understeer and oversteer. [37] Understeer occurs when the car's front wheels do not have enough traction to make the car turn and oversteer occurs when the car turns more than intended, causing the car to spin out. [ 37 ]

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 ...
