The invention discloses a brake pedal structure. The lower end of a pedal arm is pivotally assembled to the front end of a bracket; the limiting main cylinder is fixed at the rear part of the bracket; a movable rod of the limiting main cylinder is assembled and connected to the lower part or the middle part of the pedal arm; in a natural state, the pedal arm and the pedal piece are located at the initial positions through the supporting force of the movable rod of the limiting main cylinder; the electric cylinder is fixed at the rear part of the bracket and positioned on the left or right side of the limiting main cylinder; an ejector rod of the electric cylinder is connected to the lower part or the middle part of the pedal arm; when the vehicle enters the automatic driving mode, the controller controls the electric cylinder to contract the ejector rod of the electric cylinder to enable the pedal arm to rotate backwards to contract to the pedal full-stroke position; when the vehicle exits the automatic driving mode, the controller controls the electric cylinder to release the supporting force of the ejector rod of the electric cylinder and the movable rod of the limiting main cylinder so that the pedal arm and the pedal piece can rotate forwards to return to the initial position. According to the brake pedal structure, the operation feeling of a driver during normal driving can be guaranteed, the automatic driving comfort of the driver can be improved during automatic driving, and the automatic driving safety is improved.
本发明公开了一种制动踏板结构,踏板臂的下端枢转装配到支架的前端处;限位主缸固定在支架后部;限位主缸的活动杆装配连接到踏板臂的下部或中部;在自然状态下,限位主缸的活动杆的支撑力使所述踏板臂及踏板片位于初始位置;电缸固定在支架后部并位于限位主缸的左侧或右侧;电缸的顶杆连接到踏板臂下部或中部;当车辆进入自动驾驶模式时,控制器控制电缸收缩其顶杆使踏板臂向后转动收缩到踏板全行程位置;当车辆退出自动驾驶模式时,控制器控制电缸释放其顶杆,限位主缸的活动杆的支撑力使踏板臂及踏板片向前转动回探到初始位置。本发明的制动踏板结构,既能保证正常驾驶时驾驶员操作感,又能在自动驾驶时提升驾驶员的自动驾驶舒适感,提升自动驾驶安全性。
