Abstract: A method of providing an indication of driving performance involves obtaining a forward acceleration and speed of a vehicle. A forward acceleration threshold value is identified for use in identifying excessive forward acceleration of the vehicle based on the determined speed of the vehicle. For any vehicle speed within a range of vehicle speeds, the acceleration threshold value is defined by a function based on the determined speed of the vehicle, wherein the forward acceleration threshold value according to the function varies continually with vehicle speed over the range of vehicle speeds. The determined forward acceleration of the vehicle is compared with the determined acceleration threshold value, and an indication of an excessive forward acceleration driving event is generated when the determined forward acceleration exceeds the determined acceleration threshold value.

Abstract: Vehicle battery voltage data is received from a telematics control unit (TCU) of a vehicle dining multiple driving cycles, and analysed to determine a state of health (SOH) and state of charge (SOC) of the battery. The TCU also provides data relating to the state of an ignition switch of the vehicle for use in analysing the voltage data. A starting probability factor for the vehicle is determined and monitored. Information about the ability of the battery to start the vehicle is output to the user.

Abstract: A method of determining a coasting area is disclosed, together with methods of providing coasting information to a vehicle driver; coasting being when the vehicle is allowed to decelerate or to roll without being under power. In embodiments, the coasting area is determined by: determining an end point location of a coasting area based upon a location in map data of an expected decrease in speed of a vehicle traversing a road network represented by the map data; determining a start point location of the coasting area based on at least one attribute associated with the map data proximal to the end point location; and generating coasting information indicative of the coasting area having the start point and end point locations.

Abstract: A method and apparatus for evaluating the driving of a vehicle performing a journey on a road network is disclosed. The method comprises determining a fuel usage rate and an engine speed of a vehicle, and determining when the vehicle is coasting based upon at least one of the fuel usage rate and the engine speed of the vehicle. An acceleration of the vehicle, when the vehicle is determined to be coasting, is compared with a predetermined reference acceleration, and an application of braking during the coasting is determined based on the result of the comparison. A method and apparatus is also disclosed for determining a score indicative of the relative amount of time for which the vehicle is coasting without braking during a journey.
