摘要： When there is a request for a skip downshift that transitionally establishes an intermediate speed position, a surge hydraulic pressure at the start of a torque phase during shift control toward the intermediate speed position is set so as to be lower than a surge hydraulic pressure at the start of a torque phase during shift control toward a required speed position.

摘要： Provided is a control device of a vehicle capable of suppressing a racing of input rotation speed and a shock of an automatic transmission occurring at the time of switching to a driving shift due to depression of an accelerator pedal etc. during a driven shift of the automatic transmission.
When switching to a driving state is performed during an upshift in a driven state, an input rotation speed Nin of an input shaft 32 of an automatic transmission 22 is controlled by an engagement-side engagement device to be engaged during a shift and, in this case, an instruction pressure of the engagement-side engagement device is increased to a target surge pressure Psg for a target surge time T, so that the responsiveness of the engagement-side engagement device is enhanced. This enables the suppression of the racing of the rotation speed of the input shaft 32 and the shock due to a response delay of the engagement device.摘要翻译： 本发明提供一种车辆的控制装置，该车辆的控制装置能够抑制在自动变速器的驱动变速时由于踏下油门踏板等而切换为驾驶变速时产生的自动变速器的输入转速和冲击的空转 传输。 当在从动状态下升档时执行切换到驱动状态时，自动变速器22的输入轴32的输入转速Nin由换档期间的接合侧接合装置控制以接合，并且在此 的情况下，接合侧接合装置的指令压力增加到目标喘振时间T的目标喘振压力Psg，从而提高了接合侧接合装置的响应性。 由此，能够抑制输入轴32的转速的急剧上升和因卡合装置的响应延迟而产生的冲击。

摘要： A braking force controller causes a first actuator unit to generate a target jerk when the target jerk is equal to or larger than a first jerk, causes the first actuator unit to generate the first jerk and a second actuator unit to generate a jerk obtained by subtracting the first jerk from the target jerk as an additional jerk when the target jerk is smaller than the first jerk and equal to or larger than the sum of the first jerk and a second jerk, and causes the first actuator unit to generate the first jerk and the second actuator unit to generate the second jerk as the additional jerk when the target jerk is smaller than the sum of the first jerk and the second jerk.

摘要： An electronic control unit (5) is configured to control a hydraulic pressures of engaging element and disengaging element in accordance with a preset target output shaft torque during a power-on downshift. The electronic control unit (5) is configured to delay a start of decrease in the hydraulic pressure of the disengaging element from a start of a torque phase while maintain the hydraulic pressure of the disengaging element at the start of the torque phase. The electronic control unit (5) is configured to start decreasing the hydraulic pressure of the disengaging element when the electronic control unit determines that overspeed of an input shaft (3a) is occurring during the torque phase and a predetermined condition is established.
