The present disclosure also relates to a corresponding computer implemented method and to a computer program product.
Claims17
A control system for selectively controlling operation of a vehicle, wherein the control system comprises:
- an electronic control unit (ECU) comprising:
- a first control module configured to control the vehicle within a first operational range,
- a second control module configured to control the vehicle within a second operational range, the second control module redundant to, separate from, and executed in parallel to the first control module the first operational range being a subset of the second operational range, and
- a monitoring module configured to select between the first control module and the second control module by:
- comparing operation of the vehicle with the first operational range,
- selecting the first control module at the exclusion of the second control module to control the vehicle if the vehicle is operated within the first operational range, and
- selecting the second control module at the exclusion of the first control module to control the vehicle if the vehicle is operated outside of the first operational range.

A computer implemented method for selectively controlling operation of a vehicle using a control system, wherein the control system comprises:
- an electronic control unit (ECU) comprising:
- a first control module configured to control the vehicle within a first operational range,
- a second control module configured to control the vehicle within a second operational range, the second control module redundant to, separate from, and executed in parallel to the first control module, the first operational range being a subset of the second operational range and
- a monitoring module adapted to monitor the operation of the vehicle and select between the first control module and the second control module for controlling the vehicle,
- the method comprises:
- comparing, using the monitoring module, the operation of the vehicle with the first operational range,
- selecting, using the monitoring module, the first control module over the second control module to control the vehicle if the vehicle is operated within the first operational range, and
- selecting, using the monitoring module, the second control module over the first control module to control the vehicle if the vehicle is operated outside of the first operational range.
