With brake-by-wire, it becomes fluid-free. In addition to being lighter, the synchronization of the four-wheel brakes has been improved. Since a motor is used, the motor and control board generate heat. In the future, the company plans to take measures such as allowing heat to escape to the vehicle side.
While the outer rotor type is the mainstream, they developed an in-wheel motor with an inner rotor type (direct drive type). As a result, drive efficiency and reliability are high. High torque is also achieved using an inner rotor system.
New AI etc. can be tested in the background on all Astemo users' cars. As a result, a large amount of learning data can be collected, making it possible to develop highly accurate AI.

It can generate 3D point clouds using stereo camera technology and AI. Stereo viewing is possible even between different types of cameras, so it can be combined with pre-installed vehicle cameras thus acting as a low-cost solution. Challenges include the difficulty of detecting the entire surroundings using only a camera, and how to prevent the camera from getting dirty.
Semi-active suspension that does not use a G-sensor. By using AI to learn the relationship between vehicle behavior and wheel speed, it can respond to complex road conditions. Since it does not require a dedicated sensor, it is low cost and highly versatile. It is currently in the verification stage.
By introducing SBWS, physical constraints are removed and the degree of freedom in steering wheel layout increases. It is also possible to reduce costs by standardizing parts. If the SBWS fails, it is possible to safely stop the vehicle on the roadside using the single-wheel brake. With steer-by-wire, there is no need to maintain the shape of the steering wheel, so Smart SBWS uses a dial-type handle as a new steering wheel shape.
Utilizes AI to predict the movement of oncoming vehicles up to 5 seconds in advance, enabling cooperative action on narrow roads. When faced with an oncoming car, it will decide where to take shelter on its own. Uses NVIDIA Jetson for calculations.
They focus on camera-only detection without radar. Motorcycle ADAS cannot intervene with the brakes due to the risk of the rider being thrown off, so warnings are the main focus. The challenge is how to communicate this to passengers. Also, camera placement that does not spoil the appearance is very important. In the future, they are looking to realize posture control assist.
By applying the container technology used in software development to automotive software, it will be possible to more easily implement various systems.
Acquire information from maps and cameras and store it in the cloud. The information obtained is used to provide assistance tailored to the driver's skill level, as well as to perform thermal and mode control tailored to the driving environment.
- Solenoid valves have been downsized, making them applicable not only to large vehicles but also to small vehicles. It is 28% smaller than the previous model.
