Abstract
Abstract A meter for indicating the acceleration of a road vehicle has a speed-sensing means which produces an electrical signal representing the speed of the vehicle. This signal is then applied to a differentiating circuit, and the output from the differentiating circuit whereby the indicator reads the maximum acceleration or the maximum deceleration depending on the position of the switch means is applied to an indicator. The acceleration can be a positive acceleration or a negative acceleration.
