The invention discloses a brake identification protection control method and system for a wheel excavator, and belongs to the technical field of tire type engineering machinery. The method comprises the steps of obtaining a rotating speed value or a brake pressure value or a current vehicle driving state of a vehicle; vehicle acceleration is calculated according to the rotating speed value of the vehicle, and braking recognition protection control is conducted according to the vehicle acceleration; or in response to the fact that the brake pressure value is larger than the pressure threshold value, the vehicle brake state is obtained, and brake recognition protection control is conducted according to the vehicle brake state; or when the current vehicle driving state is in a downhill state in response, the pressure value of the brake oil source is obtained, and brake recognition protection control is conducted according to the pressure value of the brake oil source; according to the invention, non-standard driving and braking under the long downhill working condition of a driver can be identified, and when the braking reaches a limit value, the gear is automatically controlled for auxiliary braking, so that the abrasion of a brake pad is reduced, and the service life and the reliability of a braking mechanism are improved.

    本发明公开一种轮式挖掘机制动识别保护控制方法及系统,属于轮胎式工程机械技术领域。其包括获取车辆的转速值或刹车压力值或当前车辆行驶状态;根据车辆的转速值计算车辆加速度,根据车辆加速度进行制动识别保护控制;或响应于刹车压力值大于压力阀值,获取车辆刹车状态,根据车辆刹车状态进行制动识别保护控制;或响应于所述当前车辆行驶状态为下坡状态时,获取制动油源压力值,根据制动油源压力值进行制动识别保护控制;本发明,能够识别司机长下坡工况下的不规范驾驶和制动,当制动达到极限值时自动控制挡位进行辅助制动,从而减轻刹车片的磨损,提高制动机构的寿命和可靠性。
