Abstract:
A vehicle comprising a motor, a transmission that enables selection of a plurality of gear ratios in a process of power transmission, and a drive shaft, which are connected with one another, said vehicle being braked by means of a torque output from said motor, said vehicle comprising:an operation unit, through an operation of which a driver of said vehicle specifies a speed reduction rate in a process of braking with said motor; a target speed reduction rate setting unit that sets a target speed reduction rate in response to the operation of said operation unit; a selection unit that selects a target gear ratio among a plurality of available gear ratios, the target gear ratio enabling the currently set target speed reduction rate to be attained by the torque of said motor; a motor driving state specification unit that specifies a target driving state of said motor, in order to enable a braking force that attains the currently set target speed reduction rate to be applied to said drive shaft; and a control unit that controls said transmission to attain the target gear ratio and drives said motor in the specified target driving state.
