[0001] The present application claims the priority of Chinese Application 202010494898.8, filed in the Chinese Patent Office on June 03, 2020.Technical Field

[0002] The present application relates to the technical field of vehicles, for example, to a control method and apparatus, a device and a storage medium.Background

[0003] With the improvement in automatic driving levels, in addition to improving the ability of automatic driving algorithms and the ability of safety redundancy, user experience must also be considered. In an automatic driving state, the role of a driver changes from the driver to a passenger, and the driving experience of other passengers in a vehicle except the driver will also be switched from the driving of the original driver to automatic driving. Therefore, the control of the vehicle by automatic driving will seriously affect the riding experience.

[0004] With regard to automatic driving on the market, a vehicle distance or maximum speed is generally adjusted independently by a combination switch, and only these two dimensions can be adjusted. Driving modes such as steering control and power output are also decoupled from automatic driving. Users can often experience only one vehicle control mode in the automatic driving state.

[0022] As at least one alternative embodiment, the step of controlling the vehicle to perform automatic driving according to the driving policy corresponding to the current automatic driving mode includes: if the automatic driving mode is the personalized style driving mode, a current user driving style parameter acquisition request is sent to a Telematics service provider (Telematics Service Provider, TSP) platform; driving style parameters fed back by the TSP platform is received, and an automatic driving policy is formulated according to the driving style parameters; and the vehicle is controlled to perform automatic driving according to the automatic driving policy.

[0023] As at least one alternative embodiment, the step of acquiring the current automatic driving mode includes: an automatic driving mode input by the user into an HMI setting interface is acquired.

[0024] In one example, in step S1, the driver sets the automatic driving mode through the HMI, and there are four configurable modes in total, including a conservative style, a conventional style, an aggressive style and a personalized style. The user may set the automatic driving style when automatic driving is not activated, and may also switch the automatic driving style through the HMI in an activated state of automatic driving. In step S2, the automatic driving style set by an HMI setting interaction module is received, a setting state needs to be memorized, the style may be recalled in the next power-on cycle, or a factory default style can be controlled to be the conventional style. In step S3, whether an automatic driving system is activated is determined in real time, and if the automatic driving system is activated, an automatic driving style algorithm module previously set by the user is activated in the system. In step S4, if the driver sets the conservative style or the conventional style or the aggressive style, an automatic driving control module starts an algorithm software module stored in a local module. In step S5, if the driver sets the personalized style, the current user driving style parameter acquisition request is sent to the TSP platform through a vehicle communication module. In step S6, after receiving the request, the TSP platform reads personalized driving style model parameters of the currently logged-in account. In step S7, the TSP platform sends the corresponding parameters to the automatic driving control module through the vehicle communication module. In step S8, the automatic driving control module sends a driving style-related switching request to a driving-related control module, wherein the modules receiving the switching request from the automatic driving control module include a lane change control module, a vehicle following distance policy module, an acceleration policy module, a deceleration policy module and a maximum speed policy module. In step S9, the lane change control module receives a control request from the automatic driving control module, and switches to an automatic driving style state set by the user.

[0025] With regard to the lane change policy, different driving modes correspond to different lane change policies, as shown in Table 1 below: Table 1Lane change decision makingLane change path planningConservative style driving modeIf not necessary, no lane change decision making is performed, and the user needs to confirm to execute lane changeThe path planning is relatively conservative, the path planning is performed only when it is determined that a lane changing space and a relative speed are very safe, and the lane change speed is low.Conventional style driving modeUnder normal circumstances, lane change decision making is performed when it is determined that the driving speed of the preceding vehicle is too slow to affect the passing efficiency, and the user does not need to click for confirmation to execute automatic lane changeAccording to a conventional path planning policy, a lane change path can be planned when safety conditions are met, and the lane change speed is higher than that of the conservative styleAggressive style driving modeThe lane change decision making is performed frequently with the target of the maximum travelling efficiency, and the user does not need to confirm to execute automatic lane changeThe path planning is the most aggressive, and on the premise of meeting the safety conditions and with the target of improving the efficiency, lane change planning is executed quicklyPersonalized style driving modeA personalized lane change policy model is formulated according to usual driving habits of the corresponding userA personalized lane change path planning model is formulated according to the usual driving habits of the user

[0026] With regard to the acceleration policy and the deceleration policy, different driving modes corresponding to different acceleration policies and deceleration policies, as shown in Table 2: Table 2Acceleration policyDeceleration policyConservative style driving modeThe acceleration response during the starting and driving process is relatively slow, and the acceleration rising slope is relatively gentleA deceleration upper limit is the lowest, and the deceleration slope is relatively gentleConventional style driving modeThe acceleration response during the starting and driving process is moderate, and the acceleration rising slope is at a moderate levelThe deceleration upper limit is moderate, and the deceleration slope is normalAggressive style driving modeThe acceleration response during the starting and driving process is relatively fast, and the acceleration rising slope is relatively aggressiveThe deceleration upper limit is the highest, and the deceleration slope is relatively aggressivePersonalized style driving modeA personalized acceleration control response curve is formulated according to the usual driving habits of the corresponding userA personalized acceleration control response curve is formulated according to the usual driving habits of the corresponding user

[0027] In different automatic driving style states, response speeds and control slopes of steering control are different. The aggressive style has the fastest response and the most aggressive control; the conservative style has the slowest response and the most gentle control; and the personalized self-learning style formulates the personalized acceleration control response curve according to the usual driving habits of the user. With regard to the vehicle following distance policy and the maximum speed policy, different driving modes correspond to different following distance policies and maximum speed policies, as shown in Table 3: Table 3Vehicle following distance control moduleMaximum speed control moduleConservative style driving modeThe vehicle following distance is the farthest, and when the preceding vehicle stops, the distance with the preceding vehicle is also the farthest in a Standstill stateThe maximum speed is 10% lower than a current lane speed limit valueConventional style driving modeThe vehicle following distance is moderate, and when the preceding vehicle stops, the distance with the preceding vehicle is moderate in theThe maximum speed is 5% lower than the current lane speed limit valueStandstill stateAggressive style driving modeThe vehicle following distance is the closest, and when the preceding vehicle stops, the distance with the preceding vehicle is the closest in the Standstill stateThe maximum speed is equal to the current lane speed limit valuePersonalized style driving modePersonalized vehicle following distance control parameters are formulated according to the usual driving habits of the userPersonalized maximum speed control parameters are formulated according to the usual driving habits of the user

[0028] In different automatic driving modes, the adjustment conditions of an electronically controlled damping apparatus are different. In the conservative style, the electronically controlled damping apparatus is adjusted to a relatively soft state; in the conventional style, the electronically controlled damping apparatus is adjusted to a moderate state; in the aggressive style, the electronically controlled damping apparatus is adjusted to a relatively hard state; and in the personalized self-learning style, personalized control parameters of the electronically controlled damping apparatus are formulated according to the usual driving habits of the corresponding user.

[0029] The user is indicated of the current automatic driving style state by means of an HMI display module.

[0030] The embodiment of the present application proposes an automatic driving mode of level (L) 3 or more. The switching of the driving style in the automatic driving state can be realized by two methods of driver presetting or personalized self-learning, so as to adapt to the riding experience demands of different users in the automatic driving state. In a previous driving assistance system of L2 or less, the vehicle following distance and the maximum vehicle speed of the present vehicle relative to the preceding vehicle can be set through an HMI switch. In an automatic driving activated state of L3 or more, the vehicle is completely controlled by the automatic driving system. At this time, the driver changes from the driver of the vehicle to a "passenger", and an automatic driving task is not simple vehicle following control, but also includes overtaking, selecting a lane change opportunity and other driving scenarios. Therefore, a comprehensive control system is required to ensure that the passenger of the vehicle still feels comfortable and accustomed in the automatic driving state, that is, the automatic driving system should not only complete basic driving tasks, but also anthropomorphize and even exceed the driving level of excellent human drivers during a vehicle driving process.
