The invention relates to the field of new energy vehicles, and provides a reference vehicle speed estimation method and device, electronic equipment and a readable storage medium. The method comprises the steps that if a current wheel speed feature is a target wheel speed feature, a current acceleration feature is a target acceleration feature, and a current yaw feature is a target yaw feature, it is determined that a vehicle is in a hub rotating mode activation state; when the vehicle is in the rotating hub mode activation state and a wheel speed sensor is in an effective state, a first vehicle speed estimation strategy is adopted for vehicle speed estimation; and when the wheel speed sensor is in a failure state, vehicle speed estimation is carried out by adopting a second vehicle speed estimation strategy. According to the method, the reasonability of vehicle speed estimation in the rotating hub mode can be guaranteed, and the problem that the required torque is abnormal due to the situation that working conditions are mistakenly recognized during vehicle speed estimation due to unreasonable reference vehicle speed estimation is avoided.

    本申请涉及新能源汽车领域,提供了一种参考车速估算方法、装置、电子设备及可读存储介质。该方法包括:若当前轮速特征为目标轮速特征,当前加速度特征为目标加速度特征,且当前横摆特征为目标横摆特征,则确定车辆处于转毂模式激活状态;在车辆处于转毂模式激活状态下,当车轮轮速传感器为有效状态时,采用第一车速估算策略进行车速估算;当车轮轮速传感器为失效状态时,采用第二车速估算策略进行车速估算。本申请可保证在转毂模式下车速估算的合理性,避免因参考车速估算不合理而导致在车速估算时出现工况误识别的情况,从而引起需求扭矩异常等问题。
