A route planning apparatus configured to create a travel plan that includes a planned travel route for a leading vehicle to electronically tow a following vehicle using inter-vehicle communication, the route planning apparatus comprising: a receiving unit configured to receive a request to stop at a waypoint during traveling by the electronic towing, the stop-over request being input on a second information processing apparatus that is used by an occupant of the following vehicle: a searching unit configured to search, for a waypoint according to the request, the planned travel route and a surrounding region of the planned travel route; and a transmitting unit configured to transmit information regarding a found waypoint and a route to the waypoint to a first information processing apparatus that is used by an occupant of the leading vehicle.

Electronic towing system and method for controlling route planning apparatus

A control device of a vehicle is configured to control travelling of the vehicle such that the vehicle follows a preceding vehicle based on information received from the preceding vehicle, and determine, based on information regarding a cargo space of the preceding vehicle, an inter-vehicle distance to the preceding vehicle when the vehicles stop. Upon the preceding vehicle having stopped, the device stops the vehicle such that a distance between the vehicle and the preceding vehicle becomes the inter-vehicle distance determined by the device.

Vehicle and control device of the same

A control device of a vehicle is provided. The device controls travelling of the vehicle such that the vehicle follows another vehicle based on information received from the other vehicle; and determines whether to allow the vehicle to start to follow another vehicle based on at least one of whether a user of the vehicle is inside the vehicle or an instruction from the user. The processor starts to follow another vehicle in a case where the travel control circuit is allowed to follow the other vehicle.

Provided is a gear change control device of automatic transmission for vehicles. The gear change control device of automatic transmission includes a gear change control part which performs upshift gear change control and downshift gear change control of an automatic transmission according to a shift map. When an operation of a brake operation element is detected and full closure of an accelerator is detected, the gear change control part calculates, based on a change amount of a vehicle speed and a pressure of a brake master cylinder, a determination counter value for determining whether or not to execute the downshift of the automatic transmission, and when the determination counter value is equal to or greater than a threshold value (first threshold value), the gear change control part performs the downshift of the automatic transmission.

Gear change control device of automatic transmission for vehicle

A control apparatus of an automatic transmission including a plurality of planetary gear mechanisms and engaging mechanisms configured to establish a gear range by switching inputs/outputs of the plurality of planetary gear mechanisms, comprises an oil pressure supply device which supplies an oil pressure to operate the engaging mechanisms between an engaging state and a release state in which the engaging state is canceled; and a gear change controller which controls an operation state of each of the engaging mechanisms of the planetary gear mechanisms to establish one gear range of a plurality of gear ranges. The gear change controller executes gear change control of restricting the gear change to the gear range in a case in which the temperature of each of the engaging mechanisms in the gear range after the gear change is predicted to be not less than an allowable temperature.

Control apparatus and method of automatic transmission

An automatic transmission includes hydraulic friction engaging mechanisms for establishing a plurality of gears, at least one control valve for controlling oil pressures of hydraulic oils supplied to the engaging mechanisms, an oil pressure detection unit for detecting the oil pressure of the hydraulic oil supplied by the control valve, a learning unit for learning a correction value of an instructed oil pressure to the control valve such that an engaging time becomes a target engaging time, and a determination unit which determines, based on a difference between the instructed oil pressure to the valve and an oil pressure detection result obtained by the detection unit from the hydraulic oil supplied by the valve in correspondence with the instructed oil pressure, whether to exclude a control result by the instructed oil pressure from a learning target of the learning unit.

Automatic transmission

An automatic transmission includes a main shaft, a counter shaft, a transmission mechanism capable of establishing a plurality of gear ranges by switching a transmission path of a driving force transmitted from the main shaft to the counter shaft by a combination of engagement and release of a plurality of engaging mechanisms, a determination unit configured to determine whether the transmission mechanism is switching the gear range, and a switching unit configured to switch information of a moment of inertia about the main shaft, which is used for control, between first information during establishment of the gear range and second information during switching of the gear range based on a determination result of the determination unit.
