Abstract
A driver assistance method and a driver assistance apparatus are provided, which may be applied to the field of autonomous driving or intelligent driving. The driver assistance method includes: determining that a driver is in an abnormal state; determining that a first operation performed by the driver on a first terminal is an abnormal operation; and performing first processing, where the first processing includes outputting indication information and/or control information, and the indication information or the control information indicates a second operation performed on the first terminal, or the first processing includes controlling the first terminal to perform the second operation.
Claims12
A driver assistance method, comprising:
- determining, based on data provided by a driver sensor system, that a driver is in an abnormal state and identifying the abnormal state of the driver, the abnormal state comprising at least one of a physiological abnormal state, a mental abnormal state, or an attention abnormal state, the driver sensor system comprising one or more driver sensors;
- further determining, based on data provided by a first terminal sensor system while the driver is determined to be in the abnormal state, that a first operation performed by the driver on the first terminal is abnormal, the first terminal sensor system comprising one or more terminal sensors, wherein the first operation comprises controlling the first terminal to provide an instructed change in a motion state of a vehicle, and wherein the determining that the first operation is abnormal comprises determining that the first operation meets at least one of the following conditions:
- a change rate of the first operation is greater than or equal to a first threshold,
- an amplitude of the first operation is greater than or equal to a second threshold, and
- a target operation indicated by an operation decision from a first assistance system is inconsistent with the first operation;
- performing, as a response to determining that the first operation is abnormal while the driver is determined to be in the abnormal state, a second operation that adjusts the instructed change in the motion state to provide an adjusted change in the motion state of the vehicle, wherein the second operation is determined based on the identified abnormal state of the driver and the first operation performed by the driver;
- and
- controlling the vehicle to implement the adjusted change in the motion state of the vehicle.

An apparatus, comprising:
- one or more processors, and
- a non-transitory storage medium in communication with the one or more processors, the non-transitory storage medium configured to store program instructions that, responsive to being executed by the one or more processors, cause the apparatus to:
- determine, based on data provided by a driver sensor system, that a driver is in an abnormal state and identifying the abnormal state of the driver, the abnormal state comprising at least one of a physiological abnormal state, a mental abnormal state, or an attention abnormal state, the driver sensor system comprising one or more driver sensors;
- further determine, based on data provided by a first terminal sensor system while the driver is determined to be in the abnormal state, that a first operation performed by the driver on the first terminal is abnormal, the first terminal sensor system comprising one or more terminal sensors, wherein the first operation comprises controlling the first terminal to provide an instructed change in a motion state of a vehicle, and wherein the determining that the first operation is abnormal comprises determining that the first operation meets at least one of the following conditions:
- a change rate of the first operation is greater than or equal to a first threshold,
- an amplitude of the first operation is greater than or equal to a second threshold, and
- a target operation indicated by an operation decision from a first assistance system is inconsistent with the first operation;
- perform, as a response to determining that the first operation is abnormal while the driver is in the abnormal state, a second operation that adjusts the instructed change in the motion state to provide an adjusted change in the motion state of the vehicle, wherein the second operation is determined based on the identified abnormal state of the driver and the first operation performed by the driver;
- and
- controlling the vehicle to implement the adjusted change in the motion state of the vehicle.
