Abstract
An on-board system of a vehicle scans for target entities in at least one lane to a side of the vehicle and determines position and state of motion of detected target entities. From a state of the vehicle, an intention is inferred of a driver to move the vehicle into one of the at least one lane. If the on-board system detects a risk of collision between a target entity and the vehicle, then the motion of the vehicle is impeded by the system applying brakes of the vehicle and/or reducing a driving torque of the vehicle. A speed of the vehicle is monitored and a motion of the vehicle is not impeded if the speed of the vehicle is above a threshold speed.
Claims14
A vehicle driving assistance system on board a vehicle, the vehicle driving assistance system comprising:
- a scanning system configured to scan for target entities in at least one lane to a side of the vehicle and to provide target entity information that includes indications of positions of the target entities;
- and
- a data processing system connected to the scanning system to receive the target entity information, the data processing system being configured to:
- determine, based on the target entity information and vehicle information indicative of a state of the vehicle, a collision likelihood of a collision between a particular target entity and the vehicle;
- cause at least one motion control system of the vehicle to impede motion of the vehicle based on the collision likelihood being above a threshold likelihood;
- and
- allow, at a second time and based on a quantity of target entities detected by the scanning system within a pre-defined time period being above a pre-defined threshold, a driver of the vehicle to move the vehicle.
A vehicle driving assistance method comprising:
- scanning at least one lane to a side of a vehicle for target entities;
- providing target entity information that includes an indication of position of any target entity detected by the scanning;
- determining a quantity of target entities in at least one lane to a side of the vehicle;
- determining, based on the target entity information and vehicle information indicative of a state of the vehicle, a collision likelihood of a collision between a particular target entity and the vehicle;
- allowing, at a second time and based on a quantity of target entities detected by the scanning system within a pre-defined time period being above a pre-defined threshold, a driver of the vehicle to move the vehicle.
