Relationship between schemas mongodb

Hello, good afternoon! I need to develop a simple system, but I have doubts. I'm developing with nodeJs. It is a system for shared racing, where a driver, a passenger is registered. And from the driver and passenger, you can then create a race.

I'm definitely in the assembly of the mongoose schema, I'll post some code to illustrate.

Driver Schema:

var mongoose = require('mongoose')
var Schema = mongoose.Schema;

var motoristaSchema = new Schema({
    nm_Motorista: {type: String, require: true},
    dt_Nasc: {type: String, require: true},//ano, mes, dia
    cd_Cpf: {type: Number, require: true},
    ds_ModeloCarro: {type: String, require: true},
    ic_Status: {type: String,  enum: ['ATIVO', 'INATIVO']},
    sg_Sexo: {type: String}
})

var Motorista = mongoose.model("Motorista", motoristaSchema)
module.exports = Motorista

Passenger Schema:

var mongoose = require('mongoose')
var Schema = mongoose.Schema;

var passageiroSchema = new Schema({
    nm_Passageiro: {type: String, require: true},
    dt_Nasc: {type: String, require: true},//ano, mes, dia
    cd_Cpf: {type: Number, require: true},
    sg_Sexo: {type: String}
})

var Passageiro = mongoose.model("Passageiro", passageiroSchema)
module.exports = Passageiro

Race Schema (Containing error):

var mongoose = require('mongoose')
var Schema = mongoose.Schema;
var Motorista = require('./motorista')
var Passageiro = require('./passageiro')

var corridaSchema = new Schema({
    ds_Motorista: motoristaSchema,
    ds_Passageiro: passageiroSchema,//ano, mes, dia
    vl_Corrida: {type: Number, require: true}
})

var Corrida = mongoose.model("Corrida", corridaSchema)
module.exports = Corrida

Passenger and driver registration is ok, I need to create a racing schema where I then pass a driver and a passenger to persist in the bank.
