Abstract: A plurality of control maps respectively corresponding to a plurality of lever operation amounts are stored in a storage device. Each control map defines a driving force to be output from an electric motor such that the driving force corresponds to an accelerator operation amount and a vehicle speed. A control device uses a control map corresponding to an actual lever operation amount among the plurality of control maps and thereby calculates the driving force to be output from the electric motor based on an actual accelerator operation amount and an actual vehicle speed from the control map. This vehicle can alleviate discomfort caused when a driver accustomed to an engine vehicle operates an electric vehicle.

Abstract: An object of the present invention is to suppress energization deterioration due to crystal defects in a semiconductor device including SiC-MOSFET. To solve this problem, a semiconductor device of the present invention includes: an n−-type epitaxial layer formed on a main surface of an n+-type SiC substrate; a p-type termination region that is annularly formed in the n−-type epitaxial layer outside an active region; and an n-type hole annihilation region annularly formed in the n−-type epitaxial layer outside the p-type termination region, apart from the p-type termination region. Then, the n-type hole annihilation region has a first end surface facing the p-type termination region, as well as a second end surface on the opposite side of the first end surface. When a depth of the n-type hole annihilation region is dTM, a depth of the p-type termination region is dNR, a thickness of the n−-type epitaxial layer is dEpi, a distance from the first end surface of the n-type hole annihilation region to the second end surface thereof is LNR, and a distance from the first end surface of the n-type hole annihilation region to the periphery of the semiconductor substrate is |XNR|, these variables have the following relationship: dNR≤dTM, (|XNR|+dNR)≥dEpi, 0

Abstract: A control system includes an electric motor, an electric storage device, a throttle grip, a brake lever, a controller, and an acceleration/deceleration adjustment lever. The controller supplies electric power from the electric storage device to the electric motor in response to an acceleration command input by the throttle grip when the acceleration/deceleration adjustment lever is placed in a location closer to a driver than a cut-off position to cause the electric motor to activate the rear wheel, and cuts off electric power supplied to the electric motor irrespective of an operation of the throttle grip in a state in which the acceleration/deceleration adjustment lever has been operated and placed in the cut-off position.
