Abstract

A method for advising a driver of a vehicle may include measuring a plurality of parameters representing the vehicle's current handling condition and the vehicle's limit handling condition, determining a margin between the vehicle's current handling condition and limit handling condition, and initiating an alert for the driver before the vehicle achieves the limit handling condition if the margin exceeds a predetermined threshold.

First claim

What is claimed:

1. A vehicle comprising:
at least one of an electronic stability control system, anti-lock braking system and traction control system;
a plurality of sensors configured to measure parameters representing the vehicle's current handling condition and the vehicle's limit handling condition, wherein each of the parameters has upper and lower deadband thresholds defining a deadband interval within which the measured parameter may fall without the at least one electronic stability control system, anti-lock braking system and traction control system being activated; and
at least one computing device operatively arranged with the sensors and configured (i) to determine, for each of the parameters, a normalized difference between the parameter and at least one of the parameter's upper and lower deadband thresholds, (ii) to identify a minimum of the normalized differences, and (iii) to initiate an alert for a driver of the vehicle if the minimum of the normalized differences exceeds a predetermined threshold within the deadband interval.

2. The vehicle of claim 1 further comprising a haptic pedal, wherein initiating an alert for a driver of the vehicle includes activating the haptic pedal.

3. The vehicle of claim 1 further comprising at least one of an audio, visual and haptic driver interface operatively arranged with the at least one computing device, wherein initiating an alert for the driver includes activating the at least one of audio, visual and haptic driver interface.

4. The vehicle of claim 1 wherein the sensors include at least one of a yaw rate sensor, steering angle sensor, lateral acceleration sensor, longitudinal acceleration sensor, wheel speed sensor, and brake pressure sensor.

5. The vehicle of claim 1 wherein the computing device is further configured to low-pass filter the minimum of the normalized differences.
