A method and apparatus for providing an indication to a driver of a geared vehicle that the vehicle is not in an optimal gear is disclosed. The method comprises determining a current gear of the vehicle and determining a current speed of a drive unit of the vehicle. An indication is then provided to the driver of the vehicle that the vehicle is not in an optimal gear when: (i) the determined current speed of the drive unit is greater than a predetermined threshold; and (ii) the determined current gear of the vehicle is less than a maximum gear of the vehicle. A method and apparatus is also disclosed for determining a score indicative of the amount of time during a journey on a road network that a geared vehicle is driven in an optimal gear.

A method and apparatus is disclosed for evaluating the driving of a vehicle performing a journey on a road network, comprising determining at least one constant speed zone of the road network, a constant speed zone being a portion of the road network at which the vehicle can travel at a constant speed, said determination being based upon expected speeds of travel along the road network determined from positional data relating to the movements of a plurality of vehicles over time along the road network. A speed of the vehicle traversing the road network is determined at a plurality of times during the journey, and a value indicative of a consistency of the speed of the vehicle within the at least one constant speed zone is further determined.

Systems and methods are provided for controlling an amount of torque generated by an engine of a vehicle. The amount of torque may be controlled by limiting an amount of fuel or air or a combination thereof being provided to the engine. In some situations, controlling the amount of torque generated by the engine may be utilized to gradually limit the vehicle's acceleration, which in turn, may influence driver shifting strategies.

When driving a vehicle, constant speed drive may be engaged so that the vehicle can maintain, without any input from the operator, a desired speed, regardless of the slope on which the vehicle is travelling, or the load it is carrying etc. Control of working vehicles may be very demanding on the operator, so it may be desirable to minimise any additional control burdens. The present disclosure may facilitate the engagement of constant speed drive in a vehicle with a non-direct transmission system by considering the stability of a speed of the vehicle and an engine speed demand from the operator.

The present invention relates to a method for running of a vehicle, such that said vehicle comprises a combustion engine which can selectively be connected to at least one driveshaft (104, 105) to deliver driving force to said driveshaft (104, 105) for propulsion of said vehicle, said vehicle can be run in a first mode (Ml) in which it is run with said engine connected to said driveshaft (104, 105) and in which fuel supply to said engine is substantially shut off, in a second mode (M2) in which it is run with said engine disconnected from said at least one driveshaft (104, 105). In a situation where the vehicle is or will be travelling on a downgrade the method comprises - determining whether running said vehicle on said downgrade in said first mode (Ml) will result in a speed increase for said vehicle, and - running the vehicle in said second mode (M2) if it is determined that running it in said first mode (Ml) would result in a speed increase for said vehicle (100).
摘要:
A method and apparatus for providing an advised driving speed to a driver of a vehicle travelling on a road network is disclosed. The method comprises determining an advised driving speed of a vehicle for a portion of the road network currently being traversed, determining a current speed of the vehicle on the portion of the road network, and determining a speed limit and/or an expected driving speed for the portion of the road network. An indication of the advised driving speed is then provided to the driver of the vehicle when: (i) the current speed of the vehicle is greater than a first threshold value based on the advised driving speed; and (ii) the speed limit and/or the expected driving speed is greater than a second threshold value. A method and apparatus is also disclosed for determining a score indicative of the compliance of a driver of a vehicle to an advised driving speed during a journey on a road network.
