The invention provides a chassis, a power assembly, a chassis control method and an electric vehicle. According to the chassis provided by the invention, the first EPB control unit and the second EPB control unit are adopted to form dual-control braking, so that the problem that a new energy vehicle has no P-gear lock configuration can be solved, and under the condition that electronic control of an electronic parking system fails, the electric vehicle still has a parking backup function, and the requirement of 8% of uphill and downhill parking of national standard regulations is met. According to the chassis and the steering column matched with the electric power steering (EPS) and the self-response crumple protection function, operation is convenient, automatic returning can be achieved, stable linear driving is guaranteed, the self-control cooling system is matched, the arrangement space of the whole vehicle is increased, the self-control cooling system is in the optimal working state according to the motor temperature and the cooling liquid temperature, and the energy consumption of the whole vehicle is reduced.
本申请提供了一种底盘、动力总成、底盘的控制方法及电动车辆。根据本申请提供的底盘,采用第一EPB控制单元和第二EPB控制单元形成双控制动,以此可解决新能源车无P档锁配置的问题,在电子驻车系统电控失效情况下,电动车辆仍具有驻车备份功能,满足国标法规8%的上、下坡道驻停的要求。根据本申请提供的底盘,匹配电动助力转向EPS及自响应溃缩保护功能的转向管柱,操作轻便,能自动回正,保证稳定的直线行驶,匹配自控冷却系统,提升整车布置空间,依据电机温度、冷却液温度,自控冷却系统至最佳工作状态,降低整车能耗。
