Problems solved by technology
[0006] However, the P file locking mechanism has the following defects: 1. The cost is relatively high; 2. The P file locking mechanism has high requirements for the parking sequence (when parking, the car must first stop firmly, then pull up the parking brake and then hang the P Otherwise, it will lock up or cause an impact on the transmission; when unparking, the shift lever must first leave the P position, and then release the parking brake); 3. In the P position, being rear-ended will cause mechanical damage, and it will be used for a long time The parking pawl has the risk of metal fatigue fracture; 4. Electric vehicles do not have a gearbox, so it is impossible to add a P-lock mechanism to lock the gearbox to achieve parking

The system comprises a first control device, a second control device and an electronic hand brake, the first control device is in communication connection with the second control device; the first control device and the second control device are respectively in communication connection with the electronic hand brake; the first control device is arranged to acquire an external signal; the control module is used for controlling the electronic hand brake to execute parking operation according to an external signal; the second control device is arranged to acquire an external signal; the control module is used for controlling the electronic hand brake to execute parking operation according to an external signal; the first control device is further set to obtain working state information of the second control device; the second control device is further set to obtain working state information of the first control device; wherein the working state information comprises a normal working state and an abnormal working state; according to the invention, the problem of no parking brake when the electronic hand brake controller in the electronic parking system fails is solved.
Description
technical field [0001] The present invention relates to the technical field of parking systems, and in particular, to an electronic parking system, a parking method, a device and a terminal. Background technique [0002] At present, automobiles are constantly developing in the direction of electronization and intelligence. Especially in recent years, the rise of new energy vehicles has made automobile design, manufacturing, control and other aspects quite different from traditional automobiles. [0003] In terms of chassis brake control, electronic parking brake EPB is more and more widely used. EPB (Electrical ParkBrake) is an electronic parking system, which uses an electronic button to replace the traditional lever handbrake. Compared with the traditional parking brake system, EPB has the following advantages: it can realize functions such as automatic parking, automatic release, emergency braking assistance, hill start assistance, etc., which improves the comfort and co...
