US 12,325,409 B2 · Map-based braking

Abstract

Vehicle control using map-based braking includes receiving, while a driver is operating the vehicle to traverse a vehicle transportation network, vehicle operation information including at least a current speed of the vehicle, retrieving, from a planned path of an in-vehicle navigation system, an upcoming turn in a current road when the driver is using the in-vehicle navigation system, and retrieving from map data, the upcoming turn in the current road when the driver is not using tin-vehicle navigation system. Thereafter, it is determined whether, during the upcoming turn, wheels of the vehicle will maintain contact with a road surface at the current speed. A braking instruction is issued to a control system of the vehicle responsive to whether the wheels of the vehicle will maintain contact with the road surface at the current speed.

Dependent claims

An apparatus for vehicle control, the apparatus comprising:

a processor configured to:
receive, while a driver is operating the vehicle to traverse a vehicle transportation network, vehicle operation information including at least a current speed of the vehicle;
retrieve, from a planned path of an in-vehicle navigation system, an upcoming turn in a current road when the driver is using the in-vehicle navigation system, wherein the upcoming turn in the current road comprises data regarding a curve in the current road that causes the vehicle to advance along a new road different from the current road;
retrieve, from map data, the upcoming turn in the current road when the driver is not using the in-vehicle navigation system;
determine whether, during the upcoming turn, wheels of the vehicle will maintain contact with a road surface at the current speed;
and
issue a braking instruction to a control system of the vehicle responsive to whether the wheels of the vehicle will maintain contact with the road surface at the current speed.
