An automotive arithmetic device includes circuitry that calculates a first candidate route based on a vehicle external environment estimated using deep learning; sets a static safe area (SA) based on a result of recognition of a target object outside a vehicle according to a predetermined rule; and determines a target motion of the motor vehicle. The circuitry selects the first candidate route as a travel route of the motor vehicle under a condition the first candidate route is entirely within the static safe area (SA), and does not select the first candidate route as the travel route of the motor vehicle when the first candidate route at least partially deviates from the static safe area (SA).

Arithmetic operation device for vehicle

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.

Arithmetic operation system for vehicles

The present invention provides an automatic transmission control apparatus which comprises a first temperature detection device for detecting a temperature of hydraulic oil stored in an automatic transmission; an automatic transmission control device installed in a same casing as that in which the hydraulic oil is stored; a second temperature detection device for detecting a temperature of the automatic transmission control device; and a malfunction determination section for comparing the temperature of the automatic transmission control device detected by the second temperature detection device with the temperature of the hydraulic oil detected by the first temperature detection device to determine whether or not a malfunction occurs in the first temperature detection device.

Automatic transmission control apparatus

A housing slidably guides a slider, which is driven in response to selection of a shift range of an automatic transmission. Upper and lateral sides of a movable range of the slider are covered with the housing. Thereby, application of hydraulic fluid and foreign objects to guide rails is limited to limit malfunction of the slider. Furthermore, even when the hydraulic fluid and foreign objects adhere to the guide rails, the hydraulic fluid and foreign objects can be collected at ends of the movable range of the slider and can be expelled to an outside of the housing through open ends of the housing.

Range sensing apparatus

It is intended to make it possible to, even in a situation where a program and/or data to be written to a memory device of an electronic control unit provided in an automatic transmission become different in content, depending on a specification of a vehicle to be mounted with the automatic transmission, manage the electronic control unit while distinguishing only by a difference in hardware configurations thereof. Disclosed is a method which comprises: an assembling step () of assembling an automatic transmission, wherein the assembling step includes installing an electronic control unit in the automatic transmission; and a testing step () of testing the automatic transmission after completion of assembling in the assembling step (), wherein a writing step () is performed after the assembling step () and before the testing step (), to write vehicle-dependent information consisting of a program and/or data depending on a specification of a vehicle to be mounted with the automatic transmission, to a memory device of the electronic control unit installed in the automatic transmission.

Method for manufacturing automatic transmission

There is provided, in one aspect of the present description, an automatic transmission. In one example, the automatic transmission comprises a transmission case, a valve body which is arranged in the transmission case, a control valve mechanism which controls oil pressures in parts of the automatic transmission and is installed in the valve body, and a solenoid valve which is attached to the valve body and is arranged at a first side of the valve body and in the transmission case. The automatic transmission further comprises an electronic control unit which controls the solenoid valve, is attached to the valve body, and is arranged at a second side of the valve body that is opposite to the first side across the valve body.

Control apparatus for automatic transmission

An automatic transmission is provided. One embodiment of the automatic transmission may include a valve body including control valves for hydraulically controlling a friction engaging element provided within said transmission. The automatic transmission may further include an electric control unit located on said valve body for controlling gear shifting of said automatic transmission. The automatic transmission may further include a transmission case having a peripheral wall for at least partially enclosing a gear shift mechanism and an outer wall provided adjacent to said peripheral wall, wherein said electric control unit is located within a containing space surrounded by said peripheral wall, said outer wall and said valve body.
