摘要:
An electronic control unit (50) suppresses gear shifting more significantly in a second travel mode than in a first travel mode. Accordingly, frequent gear shifting of an automatic transmission (16; 204) in the second travel mode is suppressed, and superior ride quality is obtained. Meanwhile, an amount of a hysteresis in a gear shifting map is smaller in the second travel mode (gear shifting lines 2, 3) than in the first travel mode (a gear shifting line 4). Thus, duration of travel at an optimum gear stage is extended in the second travel mode, and fuel economy is improved. That is, in the second travel mode, drive power responsiveness to an acceleration and deceleration operation as in the first travel mode is unnecessary. Thus, even when gear shifting is suppressed, there is a low possibility that a driver feels a sense of discomfort.

Embodiments are disclosed for an example vehicle-to-vehicle communication system. The example vehicle-to-vehicle communication system includes a user input interface (218) configured to receive a user input (306), an inter-vehicle communication system (312) capable of communicating with a navigation system (318) of a second vehicle (704), a processor (302), and a storage device (310) storing instructions executable by the processor (302) to receive a first separation from the user of the first vehicle, the first separation being input via the user input interface. Responsive to receiving a first separation from the user of the first vehicle, instructions are further executable to determine a space cushion between the second and first vehicles, the space cushion being determined based on one more of the first separation and a second separation communicated from the second vehicle via the inter-vehicle communication system, and adjust a distance between the first and second vehicles based on the space cushion.
摘要:
The invention relates to a method for autonomous tracking of a following vehicle on the track of a leading vehicle in which the leading vehicle is controlled be an operator and a lead message is sent from the leading vehicle by means of vehicle-to-X communication, which signals the readiness for autonomous tracking of following vehicles and comprises at least one element of vehicle identification information and route information of the leading vehicle. The lead message is received by the following vehicle by means of vehicle-to-X communication and rejected by the following vehicle or confirmed with a follow message which comprises at least one element of vehicle identification information of the following vehicle. After receipt of the follow message, a first element of coordination information for coordination of the autonomous tracking is sent to the following vehicle by the leading vehicle by means of vehicle-to-X communication until an end of the autonomous tracking. The method is characterised in that a second element of coordination information is detected for coordination of the autonomous tracking by means of environment sensors of the following vehicle on the basis of movements of the leading vehicle, wherein the first and second elements of coordination information are compared by the following vehicle, wherein, in the case of a matching comparison result, the autonomous tracking is performed corresponding to the first and second elements of coordination information and wherein, in the case of a deviating comparison result, the autonomous tracking is ended. The invention further relates to a corresponding system.
