International Classification:

B60Q 1/00
G09F 9/00
G08B 1/00
G04F 8/00
F02N 11/08

US Classification:

340438, 340461, 340462, 3403099, 368 5, 1231794

Abstract:

Aspects of the present invention are directed at allowing a vehicle to idle for a predetermined amount of time before shutdown. In accordance with one embodiment, a method is provided that accepts input from the vehicle operator to initiate a countdown to vehicle shutdown. When the input is received, a countdown is initiated that is regularly updated to reflect the passage of time. During the countdown, a vehicle ignition bus is maintained in an active state and a countdown value that reflects the time remaining before shutdown is presented on a graphical display. Then, in response to expiration of the countdown, the method allows the vehicle ignition bus to transition into an inactive state.

US Classification:

701 1, 324160, 340461

Abstract:

Aspects of the present invention are directed at an enhanced display for presenting tachometer information. In accordance with one embodiment, a method is provided that causes an electronic control unit associated with a dashboard display to present the current engine speed (e.g. RPM) relative to an optimal range in which fuel efficiency is maximized. More specifically, the method includes obtaining a set of tachometer data at the electronic control unit that defines the lower and upper limits of the optimal range in which fuel efficiency is maximized. Periodically, the current engine speed may be obtained by the electronic control unit associated with the dashboard display. Then, the method causes the current engine speed to be presented on the graphical display relative to the lower and upper limits of the optimal range.

International Classification:

F02B 77/08
F02M 31/125
F02M 31/16
F02M 37/00
F02N 11/08

Abstract:

In some embodiments, a fuel temperature sensor is located proximate to a vehicle component that is expected to experience fuel gelling, such as near or within a fuel filter, in order to obtain temperature information that accurately reflects the likelihood of fuel gelling occurring within the component. The proximate fuel temperature sensor can provide more accurate temperature information for components such as fuel filters that are installed at the periphery of the vehicle, compared to other temperature sensors that measure oil temperatures or other temperatures of centrally located vehicle components. In some embodiments, the vehicle is automatically started when the temperature indicated by the fuel temperature sensor falls below a startup temperature threshold value, and is automatically stopped after a predetermined time period or after the temperature reaches a shutdown temperature threshold value.

Abstract:

An on-board vehicle computing system stores values in a memory of a first engine control unit (ECU) and stores corresponding backup values in a memory of a second ECU. In this way, the second ECU provides data backup functionality for the first ECU's data. The system may retrieve a backup value from the first ECU and restore the corresponding value in the second ECU using the backup value. In one illustrative scenario, if an original engine ECU (EECU) fails and a replacement EECU is installed, the system can retrieve backup values for vehicle speed limiter (VSL) parameters from memory in a cab ECU (CECU) and update the corresponding data in the replacement EECU with the backup values.
