Embodiment 1

[0035] A smart car brake switching method is provided. The smart car has two modes of manual driving and intelligent driving. Both the manual mode braking and the smart mode braking are carried out in the way of gear meshing transmission with the braking main shaft, and cooperate with the braking main shaft One of the manual mode braking mechanism and the intelligent mode braking mechanism is engaged with the braking main shaft under the action of electromagnetic attraction for transmission.

[0036] The engagement transmission power of the intelligent mode braking mechanism and the braking main shaft is provided by a motor-controlled toothed part and the intelligent mode braking mechanism for engagement transmission.

[0037] The brake switching method of this embodiment mainly utilizes the characteristics of electromagnetic attraction and gear meshing transmission performance, and two electromagnetic mechanisms capable of electromagnetic attraction are arranged around the bra...

Embodiment 2

[0039] A smart car is provided, which is provided with a brake switching device that can quickly and flexibly switch between the smart driving mode and the manual driving mode of the smart car, such as figure 1 As shown, the brake switching device includes an ECU (that is, an ECU controller, not shown in the figure), a brake pedal 1, a brake pedal connecting rod 2 and a brake main shaft 3, and teeth are respectively arranged on both sides of the brake main shaft 3. Part 31, a first gear type jaw type electromagnetic clutch 4 is set between one tooth portion and the brake pedal connecting rod 2, and a second gear type jaw type electromagnetic clutch 5 is set at the other tooth portion, the smart car brake switching device It also includes a power mechanism capable of controlling the meshing transmission between the second gear type jaw electromagnetic clutch 5 and the braking main shaft 3 .

[0040] The ECU is electrically connected with the first gear-type jaw electromagnetic ...

Abstract

The invention relates to the technical field of automobile braking, and discloses a brake switching method for an intelligent vehicle, a device thereof, and an intelligent vehicle. The brake switchingmethod for an intelligent vehicle includes manual and intelligent driving modes. The brake switching method is characterized in that both manual mode braking and intelligent mode braking are carriedout by gear meshing transmission with a brake spindle; and the manual mode braking mechanism and the intelligent mode braking mechanism cooperating with the brake spindle are alternatively meshed withthe brake spindle under the electromagnetic suction cooperation. The brake switching method makes full use of the electromagnetic attracting characteristics and the gear meshing transmission performance, and the brake spindle can only be braked in manual mode or intelligent mode under the action of electromagnetic attraction in the same period, and the brake can be switched between manual mode brake and intelligent mode brake by simply controlling the electromagnetic attraction state, and the brake switching is simple and fast.

Description

technical field [0001] The invention relates to the technical field of automobile braking, in particular to a smart automobile braking switching method and device thereof, and an intelligent automobile. Background technique [0002] There are generally two modes for the braking of intelligent unmanned vehicles, namely: intelligent driving mode and manual braking mode. The upper-level control system (central control computer and ECU) completes tasks such as information collection, analysis, calculation, and issuing instructions, while the underlying executive agency directly realizes vehicle control. [0003] As a part of the underlying braking system, the braking mechanism is closely related to the safe operation of the vehicle. At present, there is no relevant design for the switching device of the vehicle braking force switching between the intelligent driving mode and the manual driving mode in domestic smart cars. Improve the reliability and safety of vehicle braking. ...
