The invention discloses a self-adaptive braking method, a chip, a control device and a motor vehicle. The self-adaptive braking method comprises the steps of acquiring a driving current flowing through a motor in a moving process of the motor vehicle; determining an adjustment amount of a brake control signal according to the driving current; and determining a brake control signal according to theadjustment amount, wherein the brake control signal is configured to make the motor vehicle brake. By means of the mode, the self-adaptive braking method can obtain the driving current to determine the adjustment amount of the braking control signal, and therefore the braking control signal is used for making the motor vehicle brake, and the braking current is generated. Moreover, the adjustmentamount of the brake control signal can be adjusted according to a counter electromotive force so that an excessive brake current can be prevented from being possibly generated in the control device ofthe motor vehicle, a transistor with a common current capacity in the control device cannot be burnt out, and cost performance and reliability of the whole control device are improved.
本申请公开自适应刹车方法、芯片、控制装置及机动车,其中自适应刹车方法包括获得机动车运动过程中流经电机的驱动电流;根据驱动电流,确定刹车控制信号的调整量;根据调整量,确定刹车控制信号,刹车控制信号被配置为控制机动车进行刹车。通过上述方式,本申请自适应的刹车方法可以获得驱动电流而确定刹车控制信号的调整量,从而利用刹车控制信号来控制机动车刹车,产生刹车电流。且由于刹车控制信号的调整量可以根据反电动势调整,因此可以防止机动车的控制装置中可能产生过大的刹车电流,使得控制装置中即使采用电流能力一般的晶体管也不会烧毁,从而提高了整个控制装置的性价比和可靠性。
