Adaptive cruise is more experienced than the well-known traditional cruise. Despite the fact that traditional cruise control saves fuel and provides greater comfort for long-distance driving, the driver needs to manually turn on or off the cruise function according to the speed of the surrounding vehicle. Compared to the cruise process always maintain a constant speed, adaptive cruise can be Sensor based on actual needs to automatically adjust the speed in order to maintain a safe distance with the surrounding vehicles. Adaptive cruise mainly through the radar, camera and ray to measure the distance between objects. The same inertial sensor for the body's electronic stabilization system can also be used for adaptive cruising. This sensor can help predict the route and communicate to the obstacle detector.
The driver support system is by no means limited to the speed cruise or reversing images we are familiar with. Adaptive cruise, lane keeping and lane assist, predictive emergency braking system (AEBS), and active front wheel steering systems, all of which are part of the driver assistance system, and they all rely on inertial sensors with cameras, radars or lasers The intelligent integration ABS Sensor of these sensing systems. The inertial device is applied to the ramp assist system to prevent the uphill vehicle from dropping backward. The small scale gravitational acceleration sensor within the device can determine the inclination by measuring the gravity.
The active steering system is used to reduce the amount of change in the steering angle each time the steering tire moves. This feature provides a guarantee for more accurate and safe driving, especially on the freeway. Wherein the yaw angular velocity sensor is capable of providing information about vehicle displacement. Some of the driver assistance systems have been used in some mid-range models, not just luxury models. BMW has long been introduced to the active steering system, Ford also in its SUV models 'sharp sector' in the application of the system, in the near future, there will be more car manufacturers will be followed. The current autopilot combines a range of existing driver assist functions. Fully automatic vehicles Speed Sensor need to be well aware of the surroundings of the body and can predict other vehicles and pedestrians. Predictive technology can predict the way the vehicle is on the highway through high-precision maps and visual systems, which is much easier than in urban roads, but the latter will be realized in the near future. This kind of 'deep learning' of artificial intelligence technology for the future of automatic driving vehicles is essential.
In autopilot vehicles, positioning functions are mainly derived from the techniques used in the following two areas: robots and transportation. Using camera-like, laser and radar-like sensing systems, robotics researchers have developed a new approach to determining the relative position between the driver and the object. Robot vehicles can be based on real-time positioning and map system, drawing out the surrounding environment of the body, and their own location associated with these environments. Using the surrounding landmarks and determining the location of these landmarks on the built-in high-precision map, the location of the vehicle can be obtained accordingly.
Inertial navigation system, which can determine the acceleration and rotation angle to determine the absolute position of the vehicle changes, this technology has been in the transportation industry has been fully practiced. With the initial absolute position as the starting point, the strapdown algorithm can calculate the changed position based on the reading of the inertial sensor. Depending Throttle Position Sensor on the accuracy of the positioning, inertial navigation systems sometimes require high-performance sensors to avoid the serious consequences of subtle deviations, such as ring laser gyroscopes and fiber optic gyroscopes such optical sensors can meet the highest requirements.
