Abstract
The present invention relates to a vehicle control unit (20). The vehicle control unit (20) comprises an input (26) for detecting a start demand and a driving condition. The vehicle control module also comprises a control module (28) arranged to control an engine start attribute according to a first profile (34) and a second profile (36). The vehicle control module (20) also comprises a selection module (30) arranged to select between the first and second profiles (34, 36) based on detecting a predetermined driving condition, in response to detecting a start demand.
Claims21
A control unit for a vehicle comprising:
- an input for detecting an engine start demand corresponding to a driver intent to drive the vehicle from a standstill;
- a selection module arranged to select between a first engine start profile and a second engine start profile in dependence on a monitored condition occurring when detecting the engine start demand, wherein the first engine start profile has a higher magnitude of engine speed overshoot prior to idle than the second engine start profile and the second engine start profile has a suppressed flare prior to idle, wherein the idle exists before a launch of the vehicle;
- and
- a control module arranged to control an engine start attribute according to the first engine start profile or the second engine start profile, in response to detection of the engine start demand.
A method of controlling a vehicle attribute, the method comprising:
- detecting an engine start demand corresponding to a driver intent to drive the vehicle from a standstill;
- monitoring a condition associated with detecting the engine start demand;
- selecting between a first engine start profile and a second engine start profile in dependence on the monitored condition, wherein the first engine start profile has a higher magnitude of engine speed overshoot prior to idle than the second engine start profile and the second engine start profile has a suppressed flare prior to idle;
- and
- configuring an engine start attribute according to selecting the first engine start profile or the second engine start profile in response to detecting the engine start demand.
A control unit for a vehicle, comprising:
- an input for detecting an engine start demand corresponding to a driver intent to drive the vehicle from a standstill and a condition associated with detecting the engine start demand;
- a selection module arranged to select a first engine start profile when detecting the engine start demand at a first time of day and a second engine start profile when detecting the engine start demand at a second time of day that is different than the first time of day;
- and
- a control module arranged to control an engine start attribute according to the selected one of the first engine start profile or the second engine start profile in response to detection of the engine start demand.
