The invention discloses an electronic brake assisting power failure control method and device, an automobile and a medium, and aims to solve the technical problem that in a traditional scheme, when electronic brake assisting power fails, the pedal feeling of the automobile is obviously degraded. The method comprises the steps that the state of the electronic brake booster is monitored; according to the state of the electronic brake booster, whether the electronic brake booster fails or not is judged; when it is judged that the electronic brake booster fails, braking force compensation is conducted on the vehicle according to the current pedal travel and a pre-calibrated target pedal feeling curve, the vehicle generates expected deceleration, the target pedal feeling curve represents the corresponding relation between the pre-calibrated expected deceleration and the pedal travel, and the target pedal feeling curve represents the corresponding relation between the pre-calibrated expected deceleration and the pedal travel. And the corresponding relation between the pre-calibrated expected deceleration and the pedal force is obtained. By means of the technical means, even if the electronic brake booster loses efficacy, a driver can still feel the consistent pedal feeling, and the safety feeling and comfort of driving are improved.

    本发明公开了一种电子制动助力失效控制方法、装置、汽车及介质,用于解决传统方案中,电子制动助力失效时车辆踏板感明显降级的技术问题。方法部分包括:监测电子制动助力器状态;根据所述电子制动助力器状态,判断所述电子制动助力器是否失效;当判定所述电子制动助力器失效时,按照当前踏板行程和预先标定的目标踏板感曲线对车辆进行制动力补偿,使车辆产生预期减速度,其中,所述目标踏板感曲线表征了预先标定的预期减速度与踏板行程的对应关系,以及预先标定的预期减速度与踏板力的对应关系。通过上述技术手段,即使电子制动助力器失效,驾驶员仍然能够感受到一致的踏板感觉,提高了驾驶的安全感和舒适性。
