Abstract
A controller in a host vehicle includes a processor and a memory storing processor-executable instructions. The processor is programmed to calculate an error bound for confidence intervals of a predicted position at a future time of a target vehicle relative laterally to a current position and orientation of the host vehicle at a current time based on a current position and velocity of the target vehicle and the future time.
Claims20
A controller comprising a processor and a memory storing processor-executable instructions, wherein the processor is programmed to:
- calculate an error bound for confidence intervals of a predicted position of a target vehicle;
- and
- instruct a steering system of a host vehicle to turn based on the error bound;
- wherein the predicted position is at a future time;
- the predicted position is relative laterally to a current position and orientation of the host vehicle at a current time;
- calculating the error bound is based on a current position and velocity of the target vehicle and the future time;
- and
- the error bound is a product of the future time and a value that is constant with respect to the future time.
