Appl. No.:

12/898486

Inventors:

Matthew Eugene Fleming - Santa Ana CA, US
Avernethy Francisco - Torrance CA, US
Christopher Bartlett Gregg - Gardena CA, US

International Classification:

F16H 61/02

US Classification:

701 55

Abstract:

The present invention is directed to a method and system for adjusting a gear map. The present invention can be an automobile including a continuously variable transmission system, an ignition detecting ignition data, and/or a display unit. The continuously variable transmission system can include a continuously variable transmission, a memory storing a gear map including virtual gears, a gear adjustment mode input unit detecting gear adjustment mode data, and/or a processor. The processor can control the continuously variable transmission to operate at a desired engine speed for a specific automobile speed using the gear map. The processor can adjust the gear map using the gear adjustment mode data, and/or the ignition data. The processor can control the display unit to display information to prompt the user to supply the gear adjustment mode data.

US Classification:

701 22

Abstract:

A regenerative braking system for a vehicle utilizing diversion of energy for efficient use or maintaining consistent vehicle performance. The regenerative braking system includes a generator for producing regenerative energy during slowing and includes switches connected to a battery and a plurality of devices. A processor is connected with the battery and the switches for controlling the configuration of the switches based on a characteristic of the battery. If the battery has a state of charge exceeding a predetermined threshold, the processor controls the switches to route the regenerative energy to the other devices. The processor also controls the switches to provide regenerative energy to specific devices where it may most desirably be utilized. Heating and cooling units of the vehicle may be alternatively or simultaneously connected to receive the regenerative energy for providing consistent vehicle slowing performance when the battery state of charge exceeds the predetermined threshold.

International Classification:

G06F 19/00

US Classification:

701 334

Abstract:

A trip data management and display system for a vehicle. The system includes a processor, a memory, a user-interface and a display. During a trip traveled by the vehicle, the processor receives data from one or more systems or components. The processor receives input via the user-interface to associate a category and a filename with the received data for storage in the memory. The stored data may then be retrieved for display upon the display of the vehicle. The trip traveled by the vehicle is predefined according to user-settable parameters or is automatically determined based on vehicle characteristics. Instantaneous data corresponding to a trip currently being traveled by the vehicle may also be displayed on the display adjacent to the stored data from memory. The data stored may be managed by a user to associate it with different or multiple categories or to delete particular stored data.
