Embodiment Construction

[0018]The following disclosures describe various embodiments such as those used in means of transport for dual mode or multimode cruise or speed control systems. At least some embodiments herein relate to a computing device based on the quality and / or practicability of the data provided from one or more sensors of the vehicle (e.g., a camera mounted on the front of the vehicle) and between the operating modes for cruise control systems. In one example, the computing device of the autonomous vehicle is switched to an alternative mode of operation for degrading the sensor data in the initial mode (e.g., due to a sensor failure) and because the sensor data can not be used to measure the distance to other means of transport and can not be used to safely control the speed of the vehicle when controlling the speed of the vehicle.

[0019] Conventional means of transport provides a cruise control mechanism, the cruise control mechanism may automatically maintain the speed of the vehicl...

Abstract

The invention relates to dual mode cruise control. Systems, methods, and apparatus related to cruise control for a vehicle. In one approach, a speed for a first vehicle is controlled using data from a sensor in a first mode. The speed is controlled while maintaining at least a minimum distance from a second vehicle followed by the first vehicle. In response to determining that data from the sensor is not available to control the first vehicle (e.g., the data is not available to measure the minimum distance), the first vehicle changes from the first mode to a second mode. In the second mode, the first vehicle maintains a constant speed and / or obtains additional data from sensors and / or computing devices located external to the first vehicle. In another approach, the additional data may additionally or alternatively be obtained from a mobile device of a passenger of the first vehicle. The additional data is used to maintain a safe minimum distance from the second vehicle.

Description

Technical field [0001] In general, at least some embodiments disclosed herein relate to an electronic control system, and more precisely, but not limited to a computing system for implementing multi-mode speed control of a vehicle. Background [0002] Advanced Driver Assistance Systems (ADAS) are electronic systems that assist the driver of a vehicle while driving. ADAS improves automotive safety and road safety. ADAS systems use electronic technologies such as electronic control units and power semiconductor devices. Most road accidents occur due to human error. Automating some control of vehicles with ADAS can reduce human error and road accidents. ADAS is typically designed to automate, adapt, and enhance transportation systems for safe and improved driving. [0003] ADAS safety features are designed to avoid collisions and accidents by providing technology that alerts the driver to potential problems, or by implementing safeguards and gaining control of the vehicle. Adaptive ...
