What are the car systems?

1, AFS is an adaptive lighting system, which automatically adjusts the steering angle side of low beam according to the angle of vehicle speed and driving direction, and expands the effective lighting range when the vehicle turns. The automatic leveling function can ensure that the light always shines on the ground ahead, regardless of the load.

2. The active steering system is a gearbox installed in the steering wheel system, which adjusts the steering drive according to the vehicle speed. This system consists of a first-order planetary gear and two input shafts.

3.ABS is the full name of anti-lock braking system. The function is to automatically control the braking force of the brake when the car brakes, so that the wheels are not locked and are in a rolling state (the slip rate is about 20%), so as to ensure the maximum adhesion between the wheels and the ground.

4.EBD is an electronic braking force distribution system. EBD is actually an auxiliary function of ABS. It adds a control software to the control computer of ABS, and the mechanical system is completely consistent with ABS. It is only an effective supplement to ABS system, and generally combined with ABS can improve the efficiency of ABS.

5.TCS is a traction control system, also known as tracking control system. It is an anti-skid control system that judges whether the driving wheel slips according to the rotating speed of the driving wheel and the rotating speed of the transmission wheel, and then suppresses the rotating speed of the driving wheel when the former is greater than the latter.

Role of AFS:

When driving at night, Lexus equipped with adaptive lighting system can give drivers a good view when turning. Adaptive lighting system is helpful to alleviate driving fatigue and improve driving safety at night, especially when driving in unfamiliar continuous detours.

Functions of active steering system:

It can provide obvious advantages in function, weight and collision safety. Independent modules installed in the steering column area will not get high scores in the crash test. Relatively speaking, it is more expensive and heavier to adopt similar forms of motor and steering gear. However, it can provide higher flexibility for various vehicle structure series.

The function of EBD is to calculate the friction value of four tires at high speed due to different adhesion at the moment of braking, and then adjust the braking device to make it adjust at high speed in motion according to the set program, so as to achieve the matching of braking force and friction (traction) and ensure the stability and safety of the vehicle.

TCS mainly uses engine ignition timing, gearbox gear and oil supply system to control the slip of driving wheels. When TCS senses wheel slip, it will first change the ignition time of the engine through the engine control computer, reduce the torque output of the engine or apply braking to the wheel to prevent wheel slip.
