The invention relates to a method for diagnosing an electronic vehicle brake system, a vehicle comprising such an electronic vehicle brake system, a controller configured for diagnosing an electronic vehicle brake system, and a computer program for diagnosing an electronic vehicle brake system. The method comprises the following steps: generating a test current value and an expected braking effect value; instructing a brake power supply of the electronic brake system to supply the test current to an electric brake motor of the electronic brake system; receiving a braking effect measurement from a sensor of the vehicle; and obtaining a diagnostic result by comparing the braking effect measurement value with the expected braking effect value. Optionally, the braking effect includes an increase in power supplied from a wheel motor power source to an electric wheel motor, such as an in-wheel motor, of the vehicle.
本发明涉及用于诊断电子车辆制动系统的方法、包括这种电子车辆制动系统的车辆、被配置用于诊断电子车辆制动系统的控制器以及用于诊断电子车辆制动系统的计算机程序。方法包括以下步骤:生成测试电流值和预期制动效果值;指示电子制动系统的制动电源将测试电流供应给电子制动系统的电动制动马达;从车辆的传感器接收制动效果测量值;以及通过将制动效果测量值与预期制动效果值进行比较来获得诊断结果。可选地,制动效果包括从车轮马达电源供应给车辆的诸如轮内马达的电动车轮马达的功率的增大。
