Embodiment Construction

[0066] In the present detailed description, various embodiments of systems and methods according to the present invention have been described primarily with reference to a vehicle in the form of a car. However, the invention is equally applicable to other vehicles such as buses, trucks and the like. Thus, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; convey the scope of the invention. Like reference numerals refer to like elements throughout.

[0067] figure 1 A view conceptually illustrating the invention. figure 1 A vehicle 1 is shown driving on a road 3 . The vehicle 1 may already be fitted with sensors (not shown), such as radar, laser detection and measurement devices and / or image capture devices, for acquiring sensor data indicative of the presence of objects in the vicinity of the vehicle 1 . The target is, for example, an oncoming vehicle 7 approaching the current vehicle 1...

Abstract

The invention relates to a method and a system (40) for predicting the near-term path of a vehicle (1) and the associated output control signals. To predict sensor data, vehicle driving data and road data are collected. An input control signal indicative of a desired driving maneuver is received (S608). The sensor data and vehicle driving data are preprocessed (S610) to provide a set of target data including a previous position of each target relative to the vehicle, a time series of the target's previous heading, and a time series of the target's previous velocity. Process (S612) target data, road data, vehicle driving data, control signals and sensor data in the deep neural network. Providing (S614) a predicted path output and an output control signal based on the processing in the deep neural network.

Description

technical field [0001] The present invention relates to systems and methods for predicting the near-term path of a vehicle thereby providing associated output control signals. The invention also relates to a vehicle comprising such a system. Background technique [0002] Advanced Driver Assistance Systems (ADAS) in vehicles range from cruise control and adaptive lighting to more advanced systems such as automatic braking, automatic steering to keep the vehicle in the correct lane, and alert the driver to the presence of other cars . Typically, ADAS retrieves input data from multiple sources such as image processing from cameras, radar or laser detection and measurement devices. Recently, vehicle-to-vehicle connectivity has been on the rise with the massive increase in existing ADAS. [0003] Path prediction is an important part for advanced driver assistance systems to provide vehicles with safe and natural behavior on the road. Path prediction methods must efficiently t...
