摘要： A vehicle operating device including an operating member operable by a driver and configured to: issue, to a drive system, a command to apply a drive force in a forward direction when a first-direction operation of the operating member from its neutral position in a first direction is performed in a state in which the vehicle is at a stop or running forward; issue, to the drive system, a command to apply a drive force in a backward direction when a second-direction operation of the operating member from the neutral position in a second direction different from the first direction is performed in a state in which the vehicle is at a stop or running backward; and issue, to a brake system, a command to apply a braking force as an opposite-direction-operation-dependent braking force when the second-direction operation is performed in a state in which the vehicle is running forward.

摘要： The electric power steering apparatus according to the present disclosure includes a steering assist mechanism and a controller. The steering assist mechanism is driven by a motor and assists operation of a steering wheel by a driver. The controller acquires the position of the steering wheel and sets a target value of a steering reaction torque acting on the steering wheel. Then, the controller calculates a position target of the steering assist mechanism based on the position of the steering wheel and the target value of the steering reaction torque, and controls the motor of the steering assist mechanism according to the position target of the steering assist mechanism.

摘要： A negative pressure controller controls a negative pressure in a vacuum chamber of a vacuum booster by controlling a negative pressure supplier connected to the vacuum chamber. The negative pressure controller includes: negative pressure sensors each configured to detect the negative pressure in the vacuum chamber; and a negative-pressure-supplier controller configured to actuate the negative pressure supplier when one of output values of the negative pressure sensors which is nearest to an atmospheric pressure among the output values becomes nearer to an atmospheric pressure than a first threshold value. The negative-pressure-supplier controller is configured to stop the negative pressure supplier when at least two output values of the output values of the negative pressure sensors become nearer to a vacuum than a second threshold value.

摘要： In a situation where it is predicted that a symbol of target torque reverses by turns to be positive and negative alternately, the hybrid ECU carries out an increasing correction of the target torque, in which the target torque is corrected by increasing the target torque by a set amount ΔT in a negative direction when a specific condition, in which it is judged that the degree of the vertical vibration of a vehicle body is larger than a standard value and it is judged there is no acceleration demand, is satisfied, and makes the vibration suppression control torque not to be contained in the target torque when the specific condition is not satisfied. Thereby, even when carrying out free run, the sprung vibration suppression control can be carried out during bad road running, and braking force can be suppressed and fuel consumption can be improved during good road running.
摘要翻译： 在预测目标扭矩的符号轮流反转为正和负的情况下，混合动力ECU执行目标转矩的增加的校正，其中通过将目标转矩增加一个目标转矩来校正目标转矩 当判定车体的垂直振动程度大于标准值且判断为没有加速要求的特定条件满足设定量ΔT时，在负方向上， 当不满足特定条件时，振动抑制控制扭矩不包含在目标转矩中。 因此，即使进行自由行驶，也可以在恶劣的道路行驶期间进行弹簧振动抑制控制，并且可以抑制制动力，并且在良好的道路行驶期间可以提高燃料消耗。

摘要： The invention relates to a control device for an electrically-driven vacuum pump. The control device stops operation of an electrically-driven vacuum pump for generating negative pressure in a negative pressure chamber of a brake booster when the vacuum pump is operated and a gradient of increasing of a booster negative pressure representing a magnitude of a difference between pressure in the negative pressure chamber and the atmospheric pressure is smaller than or equal to a predetermined stop gradient threshold.
