摘要： A control apparatus includes a controller that switches a transmission mode of a transmission of a vehicle between an automatic shift mode and a temporary manual shift mode; and a storage unit storing maps each representing a relationship between a vehicle speed and an accelerator operation amount that are parameters for switching the transmission mode, and that are set for individual gradients of road on which the vehicle drives. The maps each include a cancellation region, a first maintenance region, and a second maintenance region, which are set to be different from each other according to the gradients. The controller includes a processor(s) and a memory(ies) coupled to the processor(s). The processor(s) executes a process including: selecting a map corresponding to a gradient of road on which the vehicle is driving; and switching the transmission mode based on the selected map, the vehicle speed and the accelerator operation amount.

摘要： A shift control device to be applied to a vehicle provided with an automatic transmission includes a detector and a shift mode control processor. The detector detects that the vehicle has passed through a tollgate through which the vehicle is able to pass without stopping. The shift mode control processor switches a shift mode of the vehicle from a first shift mode to a second shift mode the shift mode of the vehicle upon passing through the tollgate is the first shift mode and a predetermined condition regarding one or both of a speed of the vehicle and an accelerator opening degree of the vehicle is satisfied after the vehicle passes through the tollgate. In the first shift mode, a shift operation is performable by a driver, and in the second shift mode, a shift operation is performable by the automatic transmission.

摘要： In a method of controlling an electronic parking brake system to overcome an existing problem occurring in drive away release (DAR) mode, a control unit monitors whether or not a gear change signal is input in a vehicle stopped state, a P position state, or a parking brake applied state. When the gear change signal is input, an accelerator pedal input value of a driver is compared with a predetermined pedal input set value while a gear position of a transmission is maintained in the P position. When the accelerator pedal input value does not exceed the predetermined pedal input set value, a control operation is performed for automatic releasing of a parking brake. When a set time has passed after start of the control operation for the automatic releasing, a control operation of changing the gear position to the D position or the R position is performed.
