1. A display system for a motor vehicle comprising:
- first and second sensor means for sensing diverse vehicle operating parameters, said first sensor means generating a first input signal indicative of vehicle engine speed and said second sensor means generating a second input signal and comprising a sensor for sensing a throttle opening position;
means receiving said first and second input signal for providing a first display signal indicative of vehicle engine speed and a second display signal indicative of vehicle engine power;
vehicle display means comprising;
a plurality of display segments arranged in a matrix, a row of electrode strips arranged along an abscissa, being controllable with said first display signal and a row of electrode strips arranged along an ordinate being controllable with said second display signal, whereby at the crossing portions of the rows of electrode strips activated by the display signals a display segment is illustrated; and
a memory storing an appropriate value for the vehicle engine power, wherein a value is read out from said memory in accordance with said first and second input signals for the engine speed and throttle opening, and this value is fed to said display means as a second display signal, and a curve image overlay on said display means indicative of characteristic curves showing the maximum power with respect to the actual engine speed for predetermined positions of the throttle.
