Embodiment Construction
[0048] In order to make the purpose of the present invention, the technical solution clearer, the following in conjunction with the attached Figure 1-5 The present invention will be further described in detail by giving examples.
[0049] like figure 1 As shown, a car roll protection system based on brake-by-wire technology, including:
[0050] The signal monitoring module 1 is used for monitoring and generating a monitoring signal, and the monitoring signal includes vehicle status information related to slipping;
[0051] The vehicle controller 2 is used to determine whether the vehicle is in a rolling state according to the vehicle state information collected by the signal monitoring module, and if it is in a rolling state, send an automatic parking brake command and an alarm command to the actuator 3;
[0052] The actuator 3 is used to perform automatic parking braking and alarm prompts to realize rolling protection according to the automatic parking braking instructions...

The invention discloses a vehicle sliding protection system and method based on a brake-by-wire technology, and the system comprises a signal monitoring module which is used for monitoring and generating a monitoring signal which comprises vehicle state information related to vehicle sliding; a whole vehicle controller used for judging whether the vehicle is in a vehicle sliding state or not according to the vehicle state information collected by the signal monitoring module, and sending an automatic parking braking instruction and an alarm instruction if the vehicle is in the vehicle slidingstate; and an execution mechanism used for carrying out automatic parking braking and alarm prompting according to the automatic parking braking instruction and the alarm instruction sent by the vehicle control unit. According to the invention, the vehicle sliding alarm prompt with fixed intensity can be timely given according to the vehicle condition, and automatic parking braking is adopted based on a brake-by-wire system, so that the problem of vehicle parking braking caused by failure of a hand brake or forgetting to pull the hand brake during temporary parking of a driver is solved, the safety of parking braking is ensured, and property loss and personal safety accidents caused by vehicle sliding are avoided.
Description
technical field [0001] The invention relates to the technical field of vehicle brake-by-wire technology, in particular to a vehicle roll protection system and method based on the brake-by-wire technology. Background technique [0002] Rolling generally refers to the phenomenon that the vehicle moves forward or backward due to insufficient braking force when the vehicle is parked on a non-level road, and is called forward rolling and backward rolling respectively. On the one hand, drivers will encounter a variety of parking brake conditions in their daily driving. Due to differences in driving habits, some drivers may leave the driver's seat without pulling the handbrake or drive without pulling the handbrake when temporarily parking. When the car slides, the brake operation cannot be taken in time, resulting in serious accidents in which the door rolls over the car and even the car crashes; High, when children are playing in the car, they may accidentally trigger a switch t...
