Method and apparatus for evaluating deceleration of a vehicle

摘要

In accordance with the present inventive concept, there is provided a method for evaluating deceleration of a vehicle. The method comprises: measuring a deceleration of the vehicle during a first time interval, estimating a speed of the vehicle at a first time instant in a second time interval, which is different from the first time interval, based on the measured deceleration, measuring a speed of the vehicle at the first time instant, comparing the estimated speed to the measured speed, and generating a signal based on the comparison. There is also provided an apparatus for evaluating deceleration of a vehicle.

1. Method for evaluating deceleration of a vehicle comprising:
measuring a deceleration of the vehicle during a first time interval, determining a trend in the measured deceleration, estimating calculating a speed of the vehicle at a first time instant in a second time interval, which is different from the first time interval, based on the measured deceleration by extrapolating the trend to said first time instant, wherein the calculated speed forms an estimate of a speed the vehicle would reach had the determined trend had been maintained until said first time instant, measuring a speed of the vehicle at said first time instant, comparing the calculated speed to the measured speed, generating a signal based on said comparison, and generating a notification regarding the deceleration based on the signal.
