Abstract: A battery temperature control device for an electric vehicle is provided which is capable of maintaining both the range of the electric vehicle and the battery life at a high level without drastically reducing either of them. A recommended temperature range suitable for battery use and a usable temperature range in which a battery is usable and which is wider than the recommended temperature range are included, and while the battery temperature is basically controlled to converge to the recommended temperature range to maintain the battery life, in a situation where the power consumption necessary for controlling the battery temperature to converge to the recommended temperature is increased, making it difficult to travel a desired travelling distance, the recommended temperature range is switched to the usable temperature range and the battery temperature is controlled to converge to the usable temperature range, and the power consumption necessary for controlling the battery temperature is suppressed and the range of the vehicle is maintained.

Abstract: A vehicle control device controls a vehicle on the basis of inter-vehicle spacing information with respect to a preceding vehicle and a trailing vehicle. The vehicle control device is equipped with: a target inter-vehicle spacing calculation unit which calculates target inter-vehicle spacing information on the basis of inter-vehicle spacing information with respect to the preceding vehicle and inter-vehicle spacing information with respect to a trailing vehicle. The vehicle control device is configured to control the speed of the vehicle such that the calculated target inter-vehicle spacing information is maintained.

Abstract: The present invention provides a vehicle control device in which it is possible to modify the travel trajectory of a vehicle in response to the presence of an obstruction in the vehicle perimeter. In the present invention, the vehicle control device 1 recognizes the surroundings of the vehicle, detects a first branching point in a first route that is preset on a road, and in cases in which a prescribed condition is met by the presence of an obstruction detected from the recognized surroundings when the vehicle is to move along a travel trajectory that is based on at least one second route from among a plurality of second routes that branch from the first branching point, generates a virtual route which branches from the first route at a second branching point differing from the first branching point toward the selected second route, and modifies the travel trajectory on the basis of the generated virtual route.

Abstract: In order to prevent cell batteries from reaching a regeneration inhibiting voltage in an initial period of regeneration braking and to ensure that a large amount of regeneration can be secured even if characteristics of cell batteries are varied, when a vehicle braking request is received (S2-2), a first limit of regeneration power (S2-8) for which the amount of regeneration is relatively small is performed, and while regeneration control is being performed, information about the cell batteries such as voltage across terminals is acquired from a battery monitoring device to identify a cell battery of which the voltage across terminals becomes the highest among the multiple cell batteries. After the determination is completed (S2-5), the process proceeds to a second regeneration control (S2-9). In the second regeneration control, regeneration is performed by using an upper limit amount of regeneration with which an identified worst cell battery would not reach the regeneration inhibiting voltage as a limiting value.
