Abstract
A vehicle controller includes at least one input configured to receive sensor signals from a plurality of sensors configured to determine vehicle dynamic information and at least one input configured to receive sensor signals from a plurality of sensors configured to determine external vehicle information Included in the vehicle controller is a memory and a processor. The memory stores instructions for executing a vehicle positioning system and a driver assistance system using the controller. An output is configured to output a safe to pass condition in response to the controller determining an available vehicle power meets or exceeds an estimated power requirement for a passing operation.
Claims18
A method for determining a safe passing window for a driver of a vehicle to complete a passing operation, the method comprising:
- identifying an initiation of a passing operation by the driver of the vehicle and responding to the initiation by determining vehicle positioning information, vehicle dynamic information, and external information;
- determining an estimated power requirement based at least in part on the determined vehicle positioning information, the determined vehicle dynamic information, and the determined external information;
- comparing the estimated power requirement to an available vehicle power;
- and
- indicating a safe to pass condition in response to the available vehicle power meeting or exceeding the estimated power requirement.
A vehicle controller comprising:
- at least one input configured to receive sensor signals from a plurality of sensors configured to determine vehicle dynamic information and sensor signals from a plurality of sensors configured to determine external vehicle information;
- a memory and a processor, the memory storing instructions that are executable by the processor and that cause the processor to
- determine an initiation of a passing operation by a driver of the vehicle;
- respond to the initiation by determining vehicle positioning information, vehicle dynamic information, and external information;
- determine an estimated power requirement based at least in part on the determined vehicle positioning information, the determined vehicle dynamic information, and the determined external information;
- compare the estimated power requirement to an available vehicle power;
- and
- determine that there is a safe to pass condition in response to the available vehicle power meeting or exceeding the estimated power requirement;
- and
- an output configured to output an indication of the safe to pass condition in response to the processor determining that the safe to pass condition exists.
A non-transitory computer readable medium storing instructions for causing a vehicle controller to perform the steps of:
- determining an initiation of a passing operation by a driver of a vehicle and responding to the initiation by determining vehicle positioning information, vehicle dynamic information, and external information;
- determining an estimated power requirement based at least in part on the determined vehicle positioning information, the determined vehicle dynamic information, and the determined external information;
- comparing the estimated power requirement to an available vehicle power;
- and
- indicating a safe passing window in response to the available vehicle power meeting or exceeding the estimated power requirement.
