The invention discloses a vehicle emergency braking control circuit and a vehicle. The circuit comprises a power supply (10); the emergency stop linked switch (20) is provided with a normally closed contact (A1) and a normally open contact (A2), the first end of the normally closed contact (A1) is connected with the power supply (10), the first end of the normally open contact (A2) is grounded, and the second end of the normally open contact (A2) is connected with the second end of the normally closed contact (A1); the motor controller (30) is connected with the second end of the normally open contact (A2) and the second end of the normally closed contact (A1), and the motor controller (30) is used for controlling the vehicle to enter a preset state according to an emergency stop signal sent by the emergency stop linked switch (20) when the normally open contact (A2) is closed. According to the circuit, power-off control is carried out through hardware signals, the adhesion phenomenon of a high-voltage relay is avoided, and after a driver presses the emergency stop linked switch (20), the motor controller (30) enters a safe state to ensure safe parking.
一种车辆紧急制动控制电路及车辆,电路包括:电源(10);急停联动开关(20),急停联动开关(20)设有常闭触点(A1)和常开触点(A2),常闭触点(A1)的第一端与电源(10)连接,常开触点(A2)的第一端接地,常开触点(A2)的第二端与常闭触点(A1)的第二端连接;电机控制器(30),电机控制器(30)分别与常开触点(A2)的第二端和常闭触点(A1)的第二端连接,电机控制器(30)用于当常开触点(A2)闭合时根据急停联动开关(20)发出的急停信号控制车辆进入预设状态。该电路通过硬件信号进行断电控制,不会出现高压继电器粘连现象,驾驶员按压急停联动开关(20)后电机控制器(30)会进入安全状态以确保安全停车。
