Keyless starting and keyless entry system and working method thereof

The invention discloses a keyless starting and keyless entry system and a working method of the keyless starting and keyless entry system. The safety level of an ABS control module of the keyless starting and keyless entry system is a B level, and the safety level of a PEPS control module with a main control unit is a B level. A wheel speed collecting module comprises a fourth wheel speed sensor for collecting the wheel speed of the rear right wheel of an automobile. The ABS control module is used for transmitting the rear right wheel speed which is regarded as the automobile speed to the PEPS control module through a rigid line. The PEPS control module is used for controlling an electronic type steering lock cylinder to be unlocked to make the electronic type steering lock cylinder not to be capable of locking a direction tubular column when an ignition signal of the automobile is OFF and the automobile speed is lower than or equal to a set automobile speed threshold value. According to the keyless starting and keyless entry system and the working method of the keyless starting and keyless entry system, a safety level ASIL D is divided into a mode of ASIL B + ASIL B, and the requirement of the ASIL D of the system can be achieved. Due to the fact that the PEPS control module is simply provided with one main control module, the cost of the whole system is reduced, and the reliability of the whole PEPS system is improved at the same time.
