The invention provides an accelerator pedal opening signal failure processing method and device and related equipment.The accelerator pedal opening signal failure processing method comprises the steps that in the forward gear state or the reverse gear state and in the low-speed control state, the accelerator state is determined according to the braking state and the change information of the engine rotating speed, and the accelerator pedal opening in the accelerator state is estimated; if it is determined that the received accelerator pedal opening signal breaks down, the accelerator pedal opening used in the low-speed control state is replaced with the estimated accelerator pedal opening, and the target torque of clutch transmission control is controlled to be smaller than the sum of the torque required by a driver and the torque threshold value corresponding to the 0.2 g acceleration. The accelerator pedal opening degree is comprehensively estimated according to the braking state, the change condition of the engine rotating speed, the actual gear, the vehicle speed and the ramp gradient, and when an accelerator pedal opening degree signal received by the TCU fails, the accelerator pedal opening degree used for low-speed control of the TCU is replaced by the estimated accelerator pedal opening degree, so that the controllability of the vehicle is improved.
本发明提供了一种油门踏板开度信号失效的处理方法、装置及相关设备,包括:在前进档或倒档状态下且处于低速控制状态时,根据制动状态和发动机转速的变化信息确定油门状态,并估算所述油门状态下的油门踏板开度;如果确定接收的油门踏板开度信号出现故障,将低速控制状态下所使用的油门踏板开度替换为所估算的油门踏板开度,并控制离合器传递控制的目标扭矩小于驾驶员需求扭矩与0.2g加速度对应的扭矩阈值之和。根据制动状态、发动机转速的变化情况、实际档位、车速以及坡道坡度综合估算出油门踏板开度,当TCU接收的油门踏板开度信号失效时,TCU低速控制使用的油门踏板开度替代为估算的油门踏板开度,以此来提升车辆的可操控性。
