The invention provides a method and device for monitoring the thickness of a friction plate, a controller and a storage medium. The method comprises the steps that an auxiliary main cylinder motor is controlled to completely pump out brake fluid in a right front brake caliper and a left rear brake caliper, and the auxiliary main cylinder motor is controlled to supplement the brake fluid to the right front brake caliper; calculating the volume of the right front brake caliper according to the volume of the brake fluid supplemented to the right front brake caliper; an auxiliary main cylinder motor is controlled to supplement brake fluid to a right front brake caliper and a left rear brake caliper, and the volume of the right front brake caliper and the volume of the left rear brake caliper are calculated according to the volume of the brake fluid supplemented to the right front brake caliper and the volume of the brake fluid supplemented to the left rear brake caliper; calculating to obtain the volume of the left rear brake caliper; the volume difference between the volume of the right front brake caliper before the vehicle travels for the preset mileage and the volume of the right front brake caliper after the vehicle travels for the preset mileage is calculated, the abrasion thickness of the right front wheel friction plate is calculated according to the volume difference and the cylinder diameter of the right front piston, and real-time monitoring of the thickness of the friction plate is achieved.
本发明提供一种监测摩擦片厚度的方法、装置、控制器及存储介质,方法包括:控制副主缸电机将右前制动钳和左后制动钳中的制动液全部抽出,控制副主缸电机对右前制动钳进行制动液补液,根据对右前制动钳补液的制动液体积计算得到右前制动钳的容积;控制副主缸电机对右前制动钳和左后制动钳进行制动液补液,根据对右前制动钳和左后制动钳补液的制动液体积计算得到右前制动钳和左后制动钳的容积;计算得到左后制动钳的容积;计算车辆行驶预设里程前右前制动钳的容积与车辆行驶预设里程后右前制动钳的容积的容积差,根据容积差和右前活塞的缸径,计算得到右前轮摩擦片磨损的厚度,本发明实现了对摩擦片厚度的实时监控。
