The invention discloses an accelerator pedal torque recognition method and device. The method comprises the steps: obtaining the touch information of a touch operation after an HCU detects the touch operation of a driver for a central control screen; then, obtaining the actual position of the accelerator pedal; and then, according to the obtained touch information and the actual position of the accelerator pedal, calculating required torque of a driver, distributing the required torque to the engine and the motor as target torque, calculating a slope limit value section of torque rise, and sending the calculated slope limit value section to the engine and the motor, so that the engine and the motor output respective corresponding target torque according to the required torque of the driverand the slope limit value section of torque rise. Visibly, the corresponding torque is output according to the will of the driver; therefore, the technical problem that a driver cannot autonomously adjust the response speed and the response sensitivity of the accelerator pedal due to the fact that the output torque of the vehicle and the response speed of the vehicle to the accelerator pedal arecalculated only by analyzing the hard wire signal through the HCU is solved, and the driving experience of the driver is improved.
本申请公开了一种加速踏板扭矩识别方法及装置,当HCU检测到驾驶员对中控屏幕的触控操作后,获取该触控操作的触控信息;接着,获取到加速踏板的实际位置;然后,根据获取到的触控信息以及加速踏板的实际位置,计算出驾驶员的需求扭矩分配给发动机及电机作为目标扭矩,以及计算出扭矩上升的斜率限值区间发送给发动机及电机,以便发动机及电机根据驾驶员的需求扭矩和扭矩上升的斜率限值区间输出各自对应的目标扭矩。可见,本申请实现了按照驾驶员的意愿输出相应的扭矩,从而解决了仅依靠HCU解析硬线信号的方式来计算车辆的输出扭矩及其对加速踏板的响应速度,驾驶员无法自主调节加速踏板的响应速度及响应灵敏性的技术问题,提升了驾驶员的驾驶体验。
