Method and system for adaptive electronic driveforce unit control
First Claim
1. A driveforce system comprising:
- a weather detection unit having at least one sensor for detecting weather data;
a memory for storing a driveforce map;
an acceleration input device having an active state and an idle state; and
a processor connected to the weather detection unit, the acceleration input device, and the memory, the processor configured to analyze the weather data and determine an adjustment to the driveforce map based on the weather data, wherein the processor is configured to wait for the acceleration input device to be in the idle state before applying the adjustment to the driveforce map.

Abstract
The present invention is a method and system for adaptive electronic driveforce unit control based on the weather. An automobile can include, for example a driveforce system. The driveforce system can include a driveforce unit, an acceleration input device, a memory, a speed sensor, and/or a weather detection system. The acceleration input device can generate acceleration input data. The driveforce unit can generate an output based on the corresponding acceleration input data from a driveforce curve in a driveforce map. The driveforce map can be stored in the memory. The speed sensor can detect speed data indicating a speed and/or acceleration of the automobile. The weather detection system includes a moisture detection system detecting moisture data, a temperature sensor detecting temperature data, and a windshield wiper detection system detecting windshield wiper data. The processor adjusts the driveforce curve in the driveforce map based on the weather data.
