Systems and methods to train vehicles

Systems and methods to improve performance, reliability, learning and safety and thereby enhance autonomy of vehicles. Vehicle or head mounted human sensors are used to capture human eye movement, hearing, hand grip and contact area, and foot positions. Event signatures corresponding to human actions, reactions and responses are extracted form these sensor values and correlated to events, status and situations acquired using vehicle and outside environment sensors. These event signatures are then used to train vehicles to improve their autonomous capabilities. Signatures obtained from events are classified and stored. Performance of subjects operating vehicles are scored in response to events occurring outside the vehicles and also when there are no events, and expert drivers identified by ranking by scores or applying selection criteria. 1403 1403c 1403b A1403a 1403d 1403i 1403h h1403k fig 14c 1403i 1403b 1403j 1403g 10k 1403d fig 14c1 ...

Adaptive transmission and interference cancellation for MIMO radar

A radar system has different modes of operation. In one mode the radar operates as a single-input, multiple-output (SIMO) radar system utilizing one transmitted signal from one antenna at a time. Codes with known excellent autocorrelation properties are utilized in this mode.

In another mode, the radar operates as a MIMO radar system utilizing all the antennas at a time. Interference cancellation of the non-ideal cross correlation sidelobes when transmitting in the MIMO mode are employed to remove ghost targets due to unwanted sidelobes.

Target Detection Device For Avoiding Collision Between Vehicle And Target Captured By Sensor Mounted To The Vehicle

The target detecting device comprises a radar sensor, an imaging sensor, and an ECU. The target detected by the radar sensor is selected under certain conditions, for example, i) a reception intensity of the reflected radar waves is equal to or more than a predetermined value, or ii) the target is moving, to be outputted externally. When a stopped vehicle is detected on a road by the sensor, and a target, for example a pedestrian, present behind the stopped vehicle is detected from the image acquired by the imaging sensor by performing image recognition using predetermined patterns of a target, the ECU makes the selection condition less restrictive than the selection condition for targets other than the target present behind the stopped vehicle, or unconditionally selects the target present behind the stopped vehicle.
