本申请涉及车辆性能分析技术领域,具体涉及一种驾驶循环自动控制方法和装置。其中,方法包括发动机控制器基于接收到为挂挡状态的挂挡标志位,和自动循环控制信号的确认信号,激活自动循环工作模式;基于发动机控制器为自动循环工作模式,以及接收到对应特定工况时刻的实际车速和目标车速,计算轮端需求扭矩;基于轮端需求扭矩,计算刹车需求扭矩;发动机控制器向变速器控制器发送轮端需求扭矩,使得变速器控制器基于轮端需求扭矩控制变速;向刹车控制器发送刹车需求扭矩,使得刹车控制器基于刹车需求扭矩控制刹车变速。通过各个控制器之间的信息交互,从而实现带电子刹车的自动档车辆在整车转毂上可以自动进行预制的驾驶循环。
The invention belongs to the technical field of vehicle performance analysis and relates to a driving cycle automatic control method and device. The method comprises the steps that: an engine controller activates an automatic cycle working mode on the basis of a received gear engaging flag bit in a gear engaging state and a received confirmation signal of an automatic cycle control signal; on the basis that the engine controller is in the automatic cycle working mode and the actual vehicle speed and the target vehicle speed corresponding to a specific working condition moment are received, the wheel end demand torque is calculated; based on the wheel end demand torque, the brake demand torque is calculated; the engine controller sends the wheel end demand torque to a transmission controller, so that the transmission controller controls speed change based on the wheel end demand torque; and the brake demand torque is sent to a brake controller, so that the brake controller controls brake speed change based on the brake demand torque. Through information interaction among the controllers, the automatic transmission vehicle with the electronic brake can automatically carry out prefabricated driving circulation on the whole vehicle rotating hub.
