Vehicular driver assist system with automatic speed setting parameters

A vehicular driver assist system, the vehicular driver assist system comprising:

• a forward-viewing camera disposed at a windshield of a vehicle equipped with the vehicular driver assist system and viewing forward through the windshield of the vehicle;
• an electronic control unit (ECU) comprising electronic circuitry and associated software;
• wherein the electronic circuitry of the ECU comprises an image processor for processing image data captured by the forward-viewing camera;
• wherein the vehicular driver assist system sets an initial vehicle soft lock speed when speed of the vehicle reaches an initial threshold speed of travel;
• wherein the initial threshold speed of travel at which the vehicular driver assist system sets the initial vehicle soft lock speed is based at least in part on a speed limit of a road the vehicle is traveling along;
• wherein, with the initial vehicle soft lock speed set and with the speed of travel of the vehicle exceeding the initial vehicle soft lock speed, the vehicular driver assist system maintains the vehicle speed at the initial vehicle soft lock speed when the vehicle speed reduces to the initial vehicle soft lock speed by coasting;
• wherein the vehicular driver assist system sets an increased vehicle soft lock speed that is a multiple of a vehicle speed increment above the initial vehicle soft lock speed when the speed of the vehicle increases by the multiple of the vehicle speed increment above the initial vehicle soft lock speed;
• wherein, with the increased vehicle soft lock speed set and with the speed of travel of the vehicle exceeding the increased vehicle soft lock speed, the vehicular driver assist system maintains the vehicle speed at the increased vehicle soft lock speed when the vehicle speed reduces to the increased vehicle soft lock speed by coasting;
• and
• wherein a maximum speed setting for the increased vehicle soft lock speed is based on the speed limit of the road the vehicle is traveling along.

• an electronic control unit (ECU) comprising electronic circuitry and associated software;
• wherein the electronic circuitry of the ECU comprises an image processor for processing image data captured by the forward-viewing camera;
• wherein image data captured by the forward-viewing camera is processed at the ECU for lane marker detection and at least one selected from the group consisting of (i) traffic sign recognition, (ii) pedestrian detection and (iii) collision avoidance;
• wherein the vehicular driver assist system sets an initial vehicle soft lock speed when speed of the vehicle reaches an initial threshold speed of travel;
• wherein, with the initial vehicle soft lock speed set and with the speed of travel of the vehicle exceeding the initial vehicle soft lock speed, the vehicular driver assist system maintains the vehicle speed at the initial vehicle soft lock speed when the vehicle speed reduces to the initial vehicle soft lock speed by coasting;
