The invention discloses a vehicle, a control method of a relay in a high-voltage system of the vehicle, a medium and electronic equipment.The control method comprises the following steps that after the vehicle is powered on at an ON gear, a high-voltage power-on request is received, and a pre-charging relay and a main negative relay in the high-voltage system are controlled to be closed according to the high-voltage power-on request so that a pre-charging loop can work; acquiring a voltage value of the pre-charging loop, and calculating a first voltage average value according to the acquired voltage value every first preset time so as to obtain a plurality of first voltage average values; whether the pre-charging process before high-voltage power-on of the vehicle is successful or not is judged according to the first voltage average values; if yes, the pre-charging relay is controlled to be disconnected, and a main positive relay in the high-voltage system is controlled to be closed, so that high-voltage power-on of the vehicle is completed; and if not, fault information of failure of the pre-charging process is sent out. According to the control method, unpredictable fault phenomena generated in the operation process of the system can be reduced, and the reliability degree of the relay in the system is improved.

    本发明公开了一种车辆及其高压系统中继电器的控制方法、介质、电子设备,其中,控制方法包括以下步骤:在车辆ON档上电后,接收高压上电请求,并根据高压上电请求控制高压系统中的预充继电器和主负继电器闭合,以使预充回路进行工作;采集预充回路的电压值,并每隔第一预设时间根据采集的电压值计算第一电压平均值,以获得多个第一电压平均值;根据多个第一电压平均值判断车辆高压上电之前的预充过程是否成功;如果是,则控制预充继电器断开,并控制高压系统中的主正继电器吸合,以使车辆完成高压上电;如果否,则发出预充过程失败的故障信息。该控制方法,可减少系统在运行过程中产生无法预测的故障现象发生,提高继电器在系统中的可靠程度。
