Vehicle performance monitoring apparatus
First Claim
1. A vehicle performance monitoring apparatus for displaying the values of a plurality of performance parameters of a vehicle, said apparatus comprising sensing means for sensing data indicative of the performance of the vehicle, processing means for processing said data to derive said parameter values, memory means for storing performance information relating to said parameters, display means for displaying said parameter values, and operator command means for controlling the operation of the apparatus including the selection of which performance parameter is to be displayed on the display means and the initiation of processing routines by the processing means, one or more of the parameters being designated relative mode parameters and operation of the operator command means in a first predetermined manner causing the processing means to store in the memory means a current performance parameter value for each of said relative mode parameters as a reference value, subsequent operation of the operator command means in a second predetermined manner initiating operation of the apparatus in a relative mode in which a new current performance parameter value for each of the relative mode parameters is derived by the processing means and is displayable on the display means as a proportion of the reference value of each respective relative mode parameter.

Abstract
A vehicle performance monitoring apparatus (20) for displaying the values of a plurality of performance parameters of a vehicle (10). The apparatus includes sensors (21,22,23,24,25) for sensing data indicative of the performance of the vehicle, processing means (40,42) for processing this data to provide the parameter values, display means (35) for displaying said parameter values, and operator command means (37,38) for controlling the operation of the apparatus including the selection of which performance parameter is to be displayed on the display means and the initiation of processing routines by the processing means. Additionally the apparatus includes memory means (43,44,45) for storing performance information relating to the performance parameters and the processing means (40,42) is arranged in response to a predetermined operation of the operator command means (37,38) to store in the memory means (43,44,45) a performance parameter value for each of a number of so-called relative mode parameters. These stored values are used as reference values so that subsequently, when the apparatus is operated in so-called relative mode, the current performance parameter values for the relative mode parameters are processed by the processing means (40,42) and are each displayable on the display means (35) as proportions (e.g. percentages) of their respective reference value.
