    • Control apparatus for an electric vehicle is described, the control apparatus comprising input means operable to generate a first signal indicative of a component of a desired motion of the vehicle and a second signal independently indicative of said component; an electric motor arranged to drive a wheel of the vehicle; a controller arranged to control the motor according to said first signal; and means for generating a signal indicative of a voltage across windings of the motor, the controller further including: means for calculating a quantity indicative of a nominal expected voltage across said windings according to said second signal; means for comparing said voltage with said expected voltage; and means for generating an error signal in response to said voltage and expected voltage differing by more than a predetermined amount. A corresponding method of controlling an electric vehicle is also described.
    • 描述了一种用于电动车辆的控制装置,所述控制装置包括输入装置,其可操作以产生指示所述车辆的期望运动的分量的第一信号和独立地指示所述组件的第二信号; 布置成驱动车辆的车轮的电动马达; 控制器,被布置成根据所述第一信号控制所述电动机; 以及用于产生指示所述电动机的绕组两端的电压的信号的装置,所述控制器还包括:用于根据所述第二信号计算指示所述绕组两端的标称期望电压的量的装置; 用于将所述电压与所述预期电压进行比较的装置; 以及用于响应于所述电压和预期电压差超过预定量而产生误差信号的装置。 还描述了一种控制电动车辆的相应方法。
