Provided are a motor driving device and a motor driving system. The motor driving device is used to drive and control a motor that is a power source of an electric vehicle. The motor driving device has a slip prevention unit, which performs torque control based on the torque deviation, that is, the first slip prevention control, when hand brake information indicating closing/release of a hand brake, foot brake information indicating the closing/release of a foot brake, gear information indicating the gear position, a torque command value based on the amount of accelerator operation, and the actual rotation speed as a detection result of a motor rotation speed satisfy the first starting condition; and performs speed control to allow the speed command value to be a creep speed, that is the second slid prevention control, when a second starting condition is met while the first slip prevention control is in progress.

    提供一种马达驱动装置和马达驱动系统,所述马达驱动装置用于对作为电动汽车的动力源的马达进行驱动控制,所述马达驱动装置具有:滑落防止单元,当表示手刹的关闭/解除的手刹信息、表示脚刹的关闭/解除的脚刹信息、表示档位的档位信息、基于加速器操作量的转矩指令值、及作为马达旋转速度的检测结果的实际旋转速度满足第1起动条件时,开始进行基于转矩偏差量的转矩控制、即、第1滑落防止控制,当在正在进行所述第1滑落防止控制的状态下满足第2起动条件时,开始进行使速度指令值为缓行速度的速度控制、即、第2滑落防止控制。
