Abstract: An automotive arithmetic system includes a main arithmetic unit that generates a travel route using deep learning based on an output from a vehicle external information acquisition device; an auxiliary arithmetic unit that generates a rule-based travel route in a free space without using deep learning; a safe route generation unit that generates a safe route, which is a route that the motor vehicle takes until the motor vehicle stops at a safe stop position; and an override processing unit that prioritizes one of the travel route generated by the main arithmetic unit, the rule-based travel route generated by the auxiliary arithmetic unit, or the safe route generated by the safe route generation unit, and determines a target motion of the motor vehicle so that the motor vehicle travels on the prioritized route.

Abstract: The AC detection coil is a toroidal coil and includes plural radial-line conductors which are formed on a front face and a rear face of a substrate, conductive connection parts and conductive through-holes which connect electrically each end of radial-line conductors, wherein plural winding turns are consecutively formed by a connection of each radial-line conductor on the front and the rear faces, respectively, and include a forward coil and a backward coil, and each shape on the front and the rear faces of the radial-line conductors and the conductive connection parts are identical with each other. Consequently, when seen from a thickness direction of the substrate, areas of the forward coil and the backward coil are equal to each other, and an external, unneeded to be detected, magnetic field can be canceled each other by the forward coil and the backward coil, then a current detection accuracy can be improved.

Consequently, when seen from a thickness direction of the substrate, areas of the forward coil and the backward coil are equal to each other, and an external magnetic field, which does not need to be detected, can be canceled each other by the forward coil and the backward coil, then a current detection accuracy can be improved.

Abstract: A planetary gear transmission gear system comprises a main planetary gear train composed of a main sun gear, a main ring gear, and main planet gears. The main sun gear is driven by an input rotary shaft to rotate. A sub planetary gear train is included to have a sub sun gear, a sub ring gear, and sub planet gears, and has a different gear ratio from the main planetary gear train. The sub sun gear is connected to rotate together with the main sun gear. A common carrier supporting the main and sub planet gears is rotatable about a common center axis and is drivingly connected to rotate an output shaft. A lock mechanism releasably fixes the main ring gear in order to allow the main planet gears to rotate about the center axis as the main sun gear rotates with the main ring gear fixed. A one-way clutch is connected to permit the sub ring gear to rotate in a first direction and to prohibit the sub ring gear from rotating in a second direction opposite to the first direction.
