1 common cruise function
It cruise function: cruise control, adaptive cruise control and adaptive cruise full speed.
cruise
cruise control (Cruise Control System, CCS), is a device in the car can automatically control the traveling speed of the vehicle is mounted.
In the process of moving car, the driver can start the cruise control, then do not need to step on the gas, the vehicle can move forward at a given velocity . Usually cruise control region behind the steering wheel or integrated in the multifunction steering wheel. After opening cruise control, driver means by manual adjustment of the cruise control, the vehicle speed of the small-amplitude adjustment without throttle. When the required deceleration, the brake pedal is released automatically cruise control, the driver can then re-button previously set speed cruise recovery.
The cruise control works, the vehicle speed sensor is simply sent to the speed pulse signal and set by the cruise control means reading compared to issue instructions to adjust the server machine section increase or decrease the valve opening degree so that the vehicle speed remains set. Multifunctional electronic cruise control system aside the mechanism control section of the cable-Dingsuxunhang, completely precise electronic control, so that more precise control, to avoid the risk of mechanical failure.
An adaptive cruise
The adaptive cruise control system (Adaptive Cruise Control, ACC), is an intelligent automatic control system, the cruise control based on development of the technology Come. In addition to the driver in accordance with the set speed, but may also be implemented to maintain a predetermined distance with the car and with the distance between vehicles automatically change the acceleration and deceleration function.
Generally speaking, the adaptive cruise systemThe sensor system consists of three parts, a digital signal processor and a control module. Currently on the market common sensor is a radar sensor, an infrared beam as well as several video cameras. The signal processor is responsible for the sensor information received digital processing, the information collected the last processed by the control module controls. The system needs to decelerate is determined, the final embodiment of a wheel braking by the ABS system or approach using transmission downshift will reduce the speed.
Full adaptive cruise
Full adaptive cruise control is developed from adaptive cruise control, adaptive cruise compared to larger full range adaptive cruise operation, Bosch current generation system can operate between 0-150km / h, while the adaptive cruise usually 40-150km / h.
