These abilities considerably reduce the number of items to be verified, thus improving productivity and liberating resources that would otherwise be required for analysis in different departments. The tools can connect various sensors required to verify functions and alleviate communication delays. This is especially useful as systems gain in complexity. The dSPACE development tools allowed for a quick implementation of control algorithms developed with MATLAB В® and Simulink В®, making it possible to test new solutions immediately and adjust control parameters online. Stops, such as at an intersection, are executed on the basis of map data. Speed control is performed by comparing the speed limit data provided by the map brake control, except for emergency braking, is set for a smooth deceleration. Vehicle control in the longitudinal direction is executed by the system through speed and brake controls. Then, steering control is executed by using Yd, Оё, and additional vehicle information. The forward position of the vehicle at a future point in time and the target driving path are compared and expressed by the lateral deviation Yd and the angle Оё. The lateral control of the vehicle utilizes a forward-looking model, as illustrated in Figure 2. In addition to vehicle speed, this data is augmented by other vehicle information, which is an input for executing autonomous features and operating the actuators. For example, the function of the lane-keeping system makes highly reliable autonomous driving possible by correlating the target driving path based on the white-line recognition with the forward monitoring camera and the target driving path obtained from a high-precision map and high-precision positioning. The vehicle control system, implemented completely on the Micro-AutoBox II, analyzes a multitude of sensor and vehicle data (Figure 1), including data from autonomous driving, and infrastructure components such as the forward camera, millimeter-wave radar, high-precision GNSS (global navigation satellite system) receiver, and a high-precision map. Data received from satellite positioning systems provides the vehicle with a high level of accuracy and reliability for functions such as lane-keeping and lane-changing. By 2023, the system will operate seven satellites to enable continuous positioning. The first satellite was launched in 2010, and by 2018, the system will feature three quasi-zenith satellites and one geosynchronous satellite. The QZSS transmits its specific augmentation signals (centimeter-level augmentation information) in addition to the current positioning signals. The system makes it possible to provide a highly accurate satellite positioning service covering close to 100% of Japan, including urban canyon and mountain terrain. These satellites are placed in multiple orbital planes so that one satellite always appears near the zenith above the region of Japan. The Quasi-Zenith Satellite System (QZSS, or вЂњMICHIBIKIвЂќ) uses multiple satellites that have the same orbital period as geostationary satellites with some orbital inclinations (their orbits are known as quasi-zenith orbits). The Japanese quasi-zenith satellite positioning can be employed to obtain high levels of precision and safety. Satellite-Assisted Positioning Level 3 autonomous driving cannot be achieved with vehicle systems alone.

To verify the suitability of preventative safety technology, Mitsubishi Electric uses MicroAutoBox II, a rapid control prototyping (RCP) system from dSPACE.

For example, during highway driving, drivers can take their eyes off the road and let the vehicle take over the necessary driving functions however, drivers still need to be able to resume control after a few seconds of warning.

Level 3 vehicles are conditionally automated driving systems that perform all driving tasks, but rely on the driver to assume control in certain situations. Mitsubishi Electric is developing Diamond Safety, a technology that contributes to Level 3 autonomous vehicles. Illustration of the lateral vehicle control. Overview of the sensors for autonomous driving. With many vehicles already offering autonomous preventative safety systems, the addition of improved road infrastructure could increase the reliability and maturity of autonomous driving functions, ultimately increasing the driver's sense of safety. The rapid rise of global interest in the field of autonomous driving is ushering in a new era of automobiles.
