Abstract: A yielding action assistance system for assisting a vehicle driver to take an appropriate action in yielding to a passing emergency vehicle. The yielding action assistance system comprises: a detector that detects a proximity of the emergency vehicle; an information collector that collects a road information and information about the emergency vehicle and other vehicle; a target zone determiner that sets and updates a target zone to pull over the vehicle based on the information about the other vehicle and the road; and a notifier that informs a driver about the target zone.

Abstract: When an inertia phase has started while torque phase control is being executed, the torque phase control is ended, a target torque capacity of an engaging element in inertia phase control is corrected on the basis of a difference between the target torque capacity of the engaging element at the time when the inertia phase has started and the target torque capacity of the engaging element at the time when the torque phase control has completed (or a difference between the target torque capacity of the engaging element at the time when the inertia phase has started and the target torque capacity of the engaging element, which is set at the time when the inertia phase control has started), and the inertia phase control is started.

Abstract: In the case where the lockup clutch is in the complete engagement state when a changeover between shift stages is made with the second shift mode selected, an electronic control unit holds the lockup clutch in the complete engagement state. Meanwhile, in the case where the lockup clutch is in the slip engagement state, the electronic control unit holds the lockup clutch in the slip engagement state based on a slip amount of the torque converter, or switches the lockup clutch to the complete engagement state.

Abstract: A vehicle control system to improve acceleration response and shift feel by executing a power-on downshifting in a suitable manner. An evaluation of a skip shifting and an evaluation of a stepwise shifting are compared to each other when executing the downshifting, based on an evaluation index calculated in advance in accordance with an operating condition of an accelerator. The downshifting operation to be executed is selected from the stepwise shifting and the skip shifting whose evaluation is higher than the other one.

Abstract: 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.

Abstract: In a controller for an automatic transmission, when a jump gear shift via a plurality of intermediate shift stages is executed, a first and a second target intermediate shift stages are extracted, and a target input shaft rotation speed change rate is calculated from a difference in synchronous rotation speed between a shift stage before a current gear shift and the second target intermediate shift stage as a target shift stage of a gear shift which is executed after the current gear shift. Accordingly, it is possible to avoid a situation in which a shifting time in the gear shift control of the step before the second target intermediate shift stage becomes very short and thus packing of a clutch pack is not executed in a timely manner.

Abstract: An electronic control unit starts shift initial oil pressure control after the completion of lockup initial oil pressure control when shift control is performed during the performance of lockup control, the electronic control unit starts shift initial oil pressure control after the completion of lockup initial oil pressure control. Besides, the electronic control unit places priority on the shift control and starts the lockup initial oil pressure control after the completion of the shift initial oil pressure control, when the lockup control is performed during the performance of the shift control. Therefore, the shift initial oil pressure control and the lockup initial oil pressure control are prevented from occurring at the same time when the shift control and the lockup control are performed at the same time.

Abstract: A vehicle control system to accurately control a vehicle by estimating a position of an accelerator pedal. In a first phase of an operation of the accelerator pedal in which a depression of the accelerator pedal increases, a first predicted value of a position of the accelerator pedal is calculated by a first calculation procedure based on the position of the accelerator in the first phase. In a second phase in which the change amount of the position of the accelerator plateaus, a second predicted value of the position of the accelerator pedal is calculated by a second calculation procedure based on the position of the accelerator in the second phase. In a third phase in which the change amount of the position of the accelerator decreases, the second predicted value is employed as the predicted value of the position of the accelerator pedal.

Abstract: A vehicle control system configured to promptly shift a gear stage of a transmission during startup of an engine while reducing shocks. An engine is started by a first motor when shifting from an electric vehicle mode to a parallel hybrid vehicle mode. A controller is configured to establish a target stage via an interim stage if a shifting operation of a transmission to directly establish the target stage is expected to take longer time than a shifting operation of the transmission to establish the target stage via other stage.
